1. Panama Canal >>>>

The Panama Canal is a man-made canal in Panama which joins the Pacific and Atlantic oceans. One of the largest and most difficult engineering projects ever undertaken, it had an enormous impact on shipping between the two oceans, replacing the long and treacherous route via the Drake Passage and Cape Horn at the southernmost tip of South America. A ship sailing from New York to San Francisco via the canal travels 9,500 km (6,000 miles), well under half the 22,500 km (14,000 mile) route around Cape Horn. Although the concept of a canal near Panama dates back to the early 16th century, the first attempt to construct a canal began in 1880 under French leadership. After this attempt failed and saw 21,900 workers die, the project of building a canal was attempted and completed by the United States in the early 1900s, with the canal opening in 1914. The building of the 77 km (48 mile) canal was plagued by problems, including disease (particularly malaria and yellow fever) and landslides. By the time the canal was completed, a total of 27,500 workmen are estimated to have died in the French and American efforts.

Since opening, the canal has been enormously successful, and continues to be a key conduit for international maritime trade. The canal can accommodate vessels from small private yachts up to large commercial vessels. The maximum size of vessel that can use the canal is known as Panamax; an increasing number of modern ships exceed this limit, and are known as post-Panamax or super-Panamax vessels. A typical passage through the canal by a cargo ship takes approximately 8-10 hours. In fiscal year 2008, 14,702 vessels passed through the waterway with a total 309.6 million Panama Canal/Universal Measurement System (PC/UMS) tons.

While the Pacific Ocean is west of the isthmus and the Atlantic to the east, the journey through the canal from the Pacific to the Atlantic is one from southeast to northwest. This is a result of the isthmus's "curving back on itself" in the region of the canal. The Bridge of the Americas at the Pacific end is about a third of a degree of longitude east of the end near Colon on the Atlantic.

2. Delta Works >>>>

The Deltaworks are a series of constructions built between 1950 and 1997 in the southwest of the Netherlands to protect a large area of land around the Rhine-Meuse-Scheldt delta from the sea. The works consist of dams, sluices, locks, dikes, and storm surge barriers. The aim of the dams, sluices, and storm surge barriers was to shorten the Dutch coastline, thus reducing the number of dikes that had to be raised.

The American Society of Civil Engineers has declared the works to be one of the Seven Wonders of the Modern World together with the Zuiderzee Works.

The estuaries of the rivers Rhine, Meuse and Scheldt have been subject to many floodings over the centuries. After building the Afsluitdijk, the Dutch started studying the damming of the Rhine-Meuse Delta. Plans were developed for shortening the coastline and turning the estuary into freshwater lakes. By shortening the coastline fewer dikes would have to be reinforced.

Due to indecision and the Second World War, these plans remained studies and little action was taken. In 1950 two small estuary mouths, the Brielse Gat near Brielle and the Botlek near Vlaardingen were dammed. After the North Sea flood of 1953, a commission was installed which had to come up with a plan to research the causes and seek measures to prevent such disasters in future. They revised some of the old plans and came up with the so called "Deltaplan".

The plan consisted of blocking the estuary-mouths of the Oosterschelde, the Haringvliet and the Grevelingen. This reduced the length of the dikes exposed to the sea by approximately 400 miles (640 km). The estuary-mouths of the Nieuwe Waterweg and the Westerschelde were to remain open because of the shipping routes to the ports of Rotterdam and Antwerp. The dikes along these waterways were to be heightened and strengthened. The works would be combined with road and waterway infrastructure to stimulate the economy of the province of Zeeland and improve the connection between the port of Rotterdam and Antwerp.

3. Itaipu dam >>>>

Itaipu (Guarani: Itaipu, Portuguese: Itaipu, Spanish: Itaipú; pronounced [itaiˈpu]) is a hydroelectric dam on the Paraná River located on the border between Brazil and Paraguay.

The name "Itaipu" was taken from an isle that existed near the construction site. In the Guarani language, Itaipu means "the sound of a stone". The American composer Philip Glass has also written a symphonic cantata named Itaipu in honour of the structure.

Itaipu Binacional is a company that runs the longest operational hydroelectric power plant in the world. It is second only to the Three Gorges Dam in generating capacity. It is a binational undertaking run by Brazil and Paraguay at the Paraná River on the border section between the two countries, 15 km north of the Friendship Bridge. The project ranges from Foz do Iguaçu, in Brazil, and Ciudad del Este in Paraguay, in the south to Guaíra and Salto del Guaíra in the north. The installed generation capacity of the plant is 14 GW, with 20 generating units of 700 MW each. In the year 2008, it achieved its generating record of 94.68 billion kilowatt-hours (kWh), which supplied 90% of the energy consumed by Paraguay or 19% of that consumed by Brazil .

The concept behind Itaipu Power Plant is the result of heavy negotiations between the two countries during the 1960s. The "Ata do Iguaçu" (Iguaçu Act) was signed on July 22, 1966, by the Brazilian and Paraguayan Ministers of Foreign Affairs, Juracy Magalhães and Sapena Pastor, respectively. This was a joint declaration of the mutual interest in studying the exploitation of the hydric resources that the two countries shared in the section of the Paraná River starting from and including the Salto de Sete Quedas to the Iguaçu River's watershed. The Treaty that gave origin to the power plant was signed in 1973.

4. Golden Gate Bridge >>>>

The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the opening of the San Francisco Bay onto the Pacific Ocean. As part of both U.S. Route 101 and State Route 1, it connects the city of San Francisco on the northern tip of the San Francisco Peninsula to Marin County. The Golden Gate Bridge had the longest suspension bridge span in the world when it was completed in 1937, and has become an internationally recognized symbol of San Francisco and California. Since its completion, the span length has been surpassed by eight other bridges. It still has the second longest suspension bridge main span in the United States, after the Verrazano-Narrows Bridge in New York City. In 2007, it was ranked fifth on the List of America's Favorite Architecture by the American Institute of Architects.

Before the bridge was built, the only practical short route between San Francisco and what is now Marin County was by boat across a section of San Francisco Bay. Ferry service began as early as 1820, with regularly scheduled service beginning in the 1840s for purposes of transporting water to San Francisco. The Sausalito Land and Ferry Company service launched in 1868, which eventually became the Golden Gate Ferry Company, a Southern Pacific Railroad subsidiary, the largest ferry operation in the world by the late 1920s. Once for railroad passengers and customers only, Southern Pacific's automobile ferries became very profitable and important to the regional economy. The ferry crossing between the Hyde Street Pier in San Francisco and Sausalito in Marin County took approximately 20 minutes and cost US$1.00 per vehicle, a price later reduced to compete with the new bridge. The trip from the Ferry Building took 27 minutes.

Many wanted to build a bridge to connect San Francisco to Marin County. San Francisco was the largest American city still served primarily by ferry boats. Because it did not have a permanent link with communities around the bay, the city’s growth rate was below the national average. Many experts said that a bridge couldn’t be built across the 6,700 ft (2,042 m) strait. It had strong, swirling tides and currents, with water 335 ft (102 m) in depth at the center of the channel, and almost constant winds of 60 mph (97 km/h). Experts said that ferocious winds and blinding fogs would prevent construction and operation.

5. Empire State Building >>>>

The Empire State Building is a 102-story Art Deco skyscraper in New York City at the intersection of Fifth Avenue and West 34th Street. Its name is derived from the nickname for the state of New York. It stood as the world's tallest building for more than forty years, from its completion in 1931 until construction of the World Trade Center's North Tower was completed in 1972. Following the destruction of the World Trade Center in 2001, the Empire State Building again became the tallest building in New York City and New York State.

The Empire State Building has been named by the American Society of Civil Engineers as one of the Seven Wonders of the Modern World. The building and its street floor interior are designated landmarks of the New York City Landmarks Preservation Commission, and confirmed by the New York City Board of Estimate. It was designated as a National Historic Landmark in 1986. In 2007, it was ranked number one on the List of America's Favorite Architecture according to the AIA. The building is owned and managed by W&H Properties.

The Empire State Building is the second tallest skyscraper in th

e Americas (surpassed only by the Sears Tower) and the 9th tallest in the World. It is also the 4th tallest freestanding structure in the Americas and the 12th tallest in the world.

The present site of the Empire State Building was first developed as the John Thomson Farm in the late 18th century. At the time, a stream ran across the site, emptying into Sunfish Pond, located a block away. The block was occupied by the Waldorf-Astoria Hotel in the late 19th century, and was frequented by The Four Hundred, the social elite of New York.

6. CN Tower >>>>

The CN Tower, located in downtown Toronto, Ontario, Canada, is a communications and observation tower standing 1,815 ft. 5 inches (553.34 m) tall. It surpassed the height of the Ostankino Tower while still under construction in 1975, becoming the tallest free-standing structure on land in the world. On September 12, 2007, after holding the record for 31 years, the CN Tower was surpassed in height by the still-under-construction Burj Dubai. It remains the tallest free-standing structure in the Americas and the signature icon of Toronto's skyline, attracting more than two million international visitors annually.

Despite the loss of its title as the world's tallest freestanding structure, the CN Tower remains a symbol of Canada in a similar manner as the Empire State Building remains a symbol of the United States.

CN originally referred to Canadian National, the railway company that built the tower. Following the railway's decision to divest non-core freight railway assets, prior to the company's privatization in 1995 it transferred the tower to the Canada Lands Company, a federal Crown corporation responsible for real estate development. Since local residents wished to retain the name CN Tower, the abbreviation is now said to expand to Canada's National Tower rather than the original Canadian National Tower; however, neither of these are commonly used.

In 1995, the CN Tower was declared one of the modern Seven Wonders of the World by the American Society of Civil Engineers. It also belongs to the World Federation of Great Towers.

The idea of the CN Tower originated from the 1968 Canadian National Railway desire to build a large TV and radio communication platform to serve the Toronto area, as well as demonstrate the strength of Canadian industry and CN in particular. These plans evolved over the next few years, and the project became official in 1972. The tower would have been part of Metro Centre (see CityPlace), a large development south of Front Street on the Railway Lands, a large railway switching yard that was being made redundant by newer yards outside the city. Key project team members were NCK Engineering as structural engineer; John Andrews Architects; Webb, Zerafa, Menkes, Housden Architects; Foundation Building Construction; and Canron

7. Channel Tunnel >>>>

The Channel Tunnel (French: Le tunnel sous la Manche), also known by the portmanteau Chunnel[1], is a 50.5-kilometre (31.4 mi) undersea rail tunnel linking Folkestone, Kent in England with Coquelles near Calais in northern France beneath the English Channel at the Strait of Dover. At its lowest point it is 75 m (250 ft) deep.[2] The Channel Tunnel has the longest undersea portion of any tunnel in the world, but the Seikan Tunnel in Japan is both longer and deeper overall, at 53.85 kilometres (33.5 mi) and 240 metres (790 ft) respectively.

The tunnel carries high-speed Eurostar passenger trains, Eurotunnel ro-ro vehicle transport and international rail freight trains. In 1996 the American Society of Civil Engineers identified the tunnel as one of the Seven Wonders of the Modern World.

Ideas for a cross-Channel fixed link existed as early as 1802 but the eventual successful project, organised by Eurotunnel, began construction in 1988, opening in 1994. The cost overran predictions by 80%, and concessionaire Eurotunnel overestimated tunnel traffic and has met financial difficulty. Fires have disrupted operation of the tunnel. Illegal immigrants and asylum seekers have used the tunnel to enter Britain, causing a minor diplomatic row over the siting of the Sangatte refugee camp, which was eventually closed in 2002.

Eleven tunnel boring machines working from both the UK and France cut through chalk marl to construct two rail tunnels and a service tunnel. Rolling stock using the tunnel includes Eurostar passenger trains based on the French TGV and vehicle shuttle wagons that are the largest in the world; the tunnel has its own fleet of service vehicles. The vehicle shuttle terminals are at Cheriton (part of Folkestone) and Coquelles, and are connected to the British and French motorways.

1. Taj Mahal >>>>

The Taj Mahal (pronounced /tɑdʒ mə'hɑl/ ---- Hindi: ताज महल; Persian/Urdu: تاج محل) is a mausoleum located in Agra, India, built by Mughal Emperor Shah Jahan in memory of his favorite wife, Mumtaz Mahal.

The Taj Mahal (also "the Taj") is considered the finest example of Mughal architecture, a style that combines elements from Persian, Ottoman, Indian, and Islamic architectural styles. In 1983, the Taj Mahal became a UNESCO World Heritage Site and was cited as "the jewel of Muslim art in India and one of the universally admired masterpieces of the world's heritage."

While the white domed marble mausoleum is its most familiar component, the Taj Mahal is actually an integrated complex of structures. Building began around 1632 and was completed around 1653, and employed thousands of artisans and craftsmen. Ustad Ahmad Lahauri is generally considered to be the principal designer of the Taj Mahal.

In 1631, Shah Jahan, emperor during the Mughal empire's period of greatest prosperity, was griefstricken when his third wife, Mumtaz Mahal, died during the birth of their fourteenth child, Gauhara Begum. The court chronicles of Shah Jahan's grief illustrates the love story traditionally held as an inspiration for Taj Mahal. The construction of Taj Mahal begun soon after Mumtaz's death with the principal mausoleum completed in 1648. The surrounding buildings and garden were finished five years later. Emperor Shah Jahan himself described the Taj in these words:

Should guilty seek asylum here,
Like one pardoned, he becomes free from sin.
Should a sinner make his way to this mansion,
All his past sins are to be washed away.
The sight of this mansion creates sorrowing sighs;
And the sun and the moon shed tears from their eyes.
In this world this edifice has been made;
To display thereby the creator's glory.

The Taj Mahal incorporates and expands on design traditions of Persian and earlier Mughal architecture. Specific inspiration came from successful Timurid and Mughal buildings including the Gur-e Amir (the tomb of Timur, progenitor of the Mughal dynasty, in Samarkand),Humayun's Tomb, Itmad-Ud-Daulah's Tomb (sometimes called the Baby Taj), and Shah Jahan's own Jama Masjid in Delhi. While earlier Mughal buildings were primarily constructed of red sandstone, Shah Jahan promoted the use of white marble inlaid with semi-precious stones, and buildings under his patronage reached new levels of refinement.

2. Leaning Tower of Pisa >>>>

The Leaning Tower of Pisa (Italian: Torre pendente di Pisa) or simply The Tower of Pisa (La Torre di Pisa) is the campanile, or freestanding bell tower, of the cathedral of the Italian city of Pisa. It is situated behind the cathedral and is the third oldest structure in Pisa's Piazza del Duomo (Cathedral Square) after the cathedral and the baptistry.

Although intended to stand vertically, the tower began leaning to the southeast soon after the onset of construction in 1173 due to a poorly laid foundation and loose substrate that has allowed the foundation to shift direction. The tower presently leans to the southwest.

The height of the tower is 55.86 m (183.27 ft) from the ground on the lowest side and 56.70 m (186.02 ft) on the highest side. The width of the walls at the base is 4.09 m (13.42 ft) and at the top 2.48 m (8.14 ft). Its weight is estimated at 14,500 metric tons (16,000 short tons). The tower has 296 or 294 steps; the seventh floor has two fewer steps on the north-facing staircase. The tower leans at an angle of 3.97 degrees. This means that the top of the tower is 3.9 metres (12 ft 10 in) from where it would stand if the tower were perfectly vertical.

The Tower of Pisa was a work of art, performed in three stages over a period of about 177 years. Construction of the first floor of the white marble campanile began on August 9, 1173, a period of military success and prosperity. This first floor is surrounded by pillars with classical capitals, leaning against blind arches.

The tower began to sink after construction progressed to the third floor in 1178. This was due to a mere three-meter foundation, set in weak, unstable subsoil. This means the design was flawed from the beginning. Construction was subsequently halted for almost a century, because the Pisans were almost continually engaged in battles with Genoa, Lucca and Florence. This allowed time for the underlying soil to settle. Otherwise, the tower would almost certainly have toppled. In 1198, clocks were temporarily installed on the third floor of the unfinished construction.

3. Hagia Sophia >>>>

Hagia Sophia (Turkish: Ayasofya, from the Greek: Αγία Σοφία, "Holy Wisdom"; Latin: Sancta Sophia or Sancta Sapientia) is a former patriarchal basilica, later a mosque, now a museum in Istanbul, Turkey. Famous in particular for its massive dome, it is considered the epitome of Byzantine architecture. It was the largest cathedral ever built in the world for nearly a thousand years, until the completion of the Seville Cathedral in 1520. The current building was originally constructed as a church between A.D. 532 and 537 on the orders of the Byzantine Emperor Justinian, and was in fact the third Church of the Holy Wisdom to occupy the site (the previous two had both been destroyed by riots). It was designed by two architects, Isidore of Miletus and Anthemius of Tralles. The Church contained a large collection of holy relics and featured, among other things, a 50 foot (15 m) silver iconostasis. It was the patriarchal church of the Patriarch of Constantinople and the religious focal point of the Eastern Orthodox Church for nearly 1000 years.

In 1453, Constantinople was conquered by the Ottoman Turks and Sultan Mehmed II ordered the building to be converted into the Ayasofya Mosque[1]. The bells, altar, iconostasis, and sacrificial vessels were removed, and many of the mosaics were eventually plastered over. The Islamic features — such as the mihrab, the minbar, and the four minarets outside — were added over the course of its history under the Ottomans. It remained as a mosque until 1935, when it was converted into a museum by the Republic of Turkey.

For almost 500 years the principal mosque of Istanbul, Hagia Sophia served as a model for many of the Ottoman mosques such as the Sultan Ahmed Mosque (Blue Mosque of Istanbul), the Şehzade Mosque, the Süleymaniye Mosque, and the Rüstem Pasha Mosque.

Although it is sometimes referred to as Saint Sophia (Greek for wisdom), the Greek name in full is Ναός τῆς Ἁγίας τοῦ Θεοῦ Σοφίας, Church of the Holy Wisdom of God, and it was dedicated to the Holy Wisdom of God rather than a specific saint named Sophia.

4. Porcelain Tower of Nanjing >>>>

The Porcelain Tower (or Porcelain Pagoda) of Nanjing (pinyin: Nánjīng Táotǎ), also known as Bao'ensi (meaning "Temple of Gratitude"), is a historical site located on the south bank of the Yangtze in Nanjing, China. It was a pagoda constructed in the 15th century, but was mostly destroyed in the 19th century during the course of the Taiping rebellion. The tower is now under reconstruction.

The tower was octagonal with a base of about 97 ft in diameter. When it was built, the tower was one of the largest buildings in China, rising up to a height of 260 feet with nine stories and a staircase in the middle of the pagoda, which spiraled upwards for 130 steps. The top of the roof was marked by a golden sphere. There were originally plans to add more stories, according to an American missionary who in 1852 visited Nanjing. There are only a few Chinese pagodas that surpass its height, such as the still existent 275 ft tall 11th century Liaodi Pagoda in Hebei or the non-existent 330 ft tall 7th century wooden pagoda of Chang'an.

The tower was built with white porcelain bricks that were said to reflect the sun's rays during the day, and at night as many as 140 lamps were hung from the building to illuminate the tower. Glazes and stoneware were worked into the porcelain and created a mixture of green, yellow, brown and white designs on the sides of the tower, including animals, flowers and landscapes. The tower was also decorated with numerous Buddhist images.

5. Great Wall of China >>>>

The Great Wall of China (simplified Chinese: ; traditional Chinese: ; pinyin: Chángchéng; literally "long city/fortress") or (simplified Chinese: ; traditional Chinese: ; pinyin: Wànlǐ Chángchéng; literally "The long wall of 10,000 Li is a series of stone and earthen fortifications in China, built, rebuilt, and maintained between the 5th century BC and the 16th century to protect the northern borders of the Chinese Empire from Xiongnu attacks during the rule of successive dynasties. Several walls, referred to as the Great Wall of China, were built since the 5th century BC. One of the most famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang; little of it remains; it was much farther north than the current wall, which was built during the Ming Dynasty.

The Great Wall stretches over approximately 6,400 km (4,000 miles) from Shanhaiguan in the east to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia, but stretches to over 6,700 km (4,160 miles) in total. At its peak, the Ming Wall was guarded by more than one million men. It has been estimated that somewhere in the range of 2 to 3 million Chinese died as part of the centuries-long project of building the wall.

The Chinese were already familiar with the techniques of wall-building by the time of the Spring and Autumn Period, which began around the 8th century BC. During the Warring States Period from the 5th century BC to 221 BC, the states of Qi, Yan and Zhao all constructed extensive fortifications to defend their own borders. Built to withstand the attack of small arms such as swords and spears, these walls were made mostly by stamping earth and gravel between board frames. Qin Shi Huang conquered all opposing states and unified China in 221 BC, establishing the Qin Dynasty. Intending to impose centralized rule and prevent the resurgence of feudal lords, he ordered the destruction of the wall sections that divided his empire along the former state borders. To protect the empire against intrusions by the Xiongnu people from the north, he ordered the building of a new wall to connect the remaining fortifications along the empire's new northern frontier. Transporting the large quantity of materials required for construction was difficult, so builders always tried to use local resources. Stones from the mountains were used over mountain ranges, while rammed earth was used for construction in the plains. There are no surviving historical records indicating the exact length and course of the Qin Dynasty walls. Most of the ancient walls have eroded away over the centuries, and very few sections remain today. Later, the Han, Sui, Northern and Jin dynasties all repaired, rebuilt, or expanded sections of the Great Wall at great cost to defend themselves against northern invaders.

6. Colosseum >>>>

The Colosseum or Roman Coliseum, originally the Flavian Amphitheatre (Latin: Amphitheatrum Flavium, Italian Anfiteatro Flavio or Colosseo), is an elliptical amphitheatre in the center of the city of Rome, Italy, the largest ever built in the Roman Empire. It is one of the greatest works of Roman architecture and Roman engineering.

Occupying a site just east of the Roman Forum, its construction started between 70 and 72 AD under the emperor Vespasian and was completed in 80 AD under Titus, with further modifications being made during Domitian's reign (81–96). The name "Amphitheatrum Flavium" derives from both Vespasian's and Titus's family name (Flavius, from the gens Flavia).

Originally capable of seating around 80,000 spectators, the Colosseum was used for gladiatorial contests and public spectacles. As well as the gladiatorial games, other public spectacles were held there, such as mock sea battles, animal hunts, executions, re-enactments of famous battles, and dramas based on Classical mythology. The building ceased to be used for entertainment in the early medieval era. It was later reused for such purposes as housing, workshops, quarters for a religious order, a fortress, a quarry, and a Christian shrine.

It has been estimated that about 500,000 people and over a million wild animals died in the Colosseum games.

Although in the 21st century it stays partially ruined due to damage caused by devastating earthquakes and stone-robbers, the Colosseum is an iconic symbol of Imperial Rome and its breakthrough achievements in earthquake engineering. It is one of Rome's most popular tourist attractions and still has close connections with the Roman Catholic Church, as each Good Friday the Pope leads a torchlit "Way of the Cross" procession to the amphitheatre.

The Colosseum is also depicted on the Italian version of the five-cent euro coin.

7. Stonehenge >>>>

Stonehenge is a prehistoric monument located in the English county of Wiltshire, about 3.2 kilometres (2.0 mi) west of Amesbury and 13 kilometres (8.1 mi) north of Salisbury. One of the most famous prehistoric sites in the world, Stonehenge is composed of earthworks surrounding a circular setting of large standing stones and sits at the centre of the densest complex of Neolithic and Bronze Age monuments in England, including several hundred burial mounds. Archaeologists had believed that the iconic stone monument was erected around 2500 BC, as described in the chronology below. However one recent theory has suggested that the first stones were not erected until 2400-2200 BC, whilst another suggests that bluestones may have been erected at the site as early as 3000 BC (see phase 1 below). The surrounding circular earth bank and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC. The site and its surroundings were added to the UNESCO's list of World Heritage Sites in 1986 in a co-listing with Avebury henge monument, and it is also a legally protected Scheduled Ancient Monument. Stonehenge itself is owned by the Crown and managed by English Heritage while the surrounding land is owned by the National Trust.

New archaeological evidence found by the Stonehenge Riverside Project indicates that Stonehenge served as a burial ground from its earliest beginnings. The dating of cremated remains found that burials took place as early as 3000 B.C, when the first ditches were being built around the monument. Burials continued at Stonehenge for at least another 500 years when the giant stones which mark the landmark were put up. According to Professor Mike Parker Pearson, head of Stonehenge Riverside Project:

“

Stonehenge was a place of burial from its beginning to its zenith in the mid third millennium B.C. The cremation burial dating to Stonehenge's sarsen stones phase is likely just one of many from this later period of the monument's use and demonstrates that it was still very much a domain of the dead.

1. Lighthouse of Alexandria >>>>

The lighthouse of Alexandria (or The Pharos of Alexandria, Greek: ὁ Φάρος τῆς Ἀλεξανδρείας) was a tower built in the 3rd century BC (between 285 and 247 BC) on the island of Pharos in Alexandria, Egypt to serve as that port's landmark, and later, its lighthouse.

With a height variously estimated at between 115 and 150 m (380 and 490 ft) it was among the tallest man-made structures on Earth for many centuries, and was identified as one of the Seven Wonders of the Ancient World by Antipater of Sidon. It may have been the third tallest building after the two Great Pyramids (of Khufu and Khafra) for its entire life. Some scholars estimate that would make the tower the tallest building up to the 14th century.

Pharos was a small island just off the coast of Alexandria. It was linked to the mainland by a man-made connection named the Heptastadion, which thus formed one side of the city's harbor. As the Egyptian coast is very flat and lacking in the kind of landmark used at the time for navigation, a marker of some sort at the mouth of the harbour was deemed necessary - a function the Pharos was initially designed to serve. Use of the building as a lighthouse, with a fire and reflective mirrors at the top, is thought to date to around the 1st century AD, during the Roman period. Prior to that time the Pharos served solely as a landmark or day beacon.

The lighthouse was completed in the 3rd century B.C., after having been initiated by Satrap (governor) Ptolemy I Soter, Egypt's first Macedonian ruler and a general of Alexander the Great. After Alexander died unexpectedly at age 32, Ptolemy Soter (Saviour, named so by the inhabitants of Rhodes) made himself king in 305 B.C. and ordered the construction of the Pharos shortly thereafter. The building was finished during the reign of his son, Ptolemy Philadelphos.

2. Colossus of Rhodes >>>>

The Colossus of Rhodes was a statue of the Greek god Helios, erected on the Greek island of Rhodes by Chares of Lindos between 292 and 280 BC. It is considered one of the Seven Wonders of the Ancient World. Before its destruction, the Colossus of Rhodes stood over 30 meters (107 ft) high, making it one of the tallest statues of the ancient world

Alexander the Great of Macedonia died at an early age in 323 BC without having had time to put into place any plans for his succession. Fighting broke out among his generals, the Diadochi, with four of them eventually dividing up much of his empire in the Mediterranean area. During the fighting, Rhodes had sided with Ptolemy, and when Ptolemy eventually took control of Egypt, Rhodes and Ptolemaic Egypt formed an alliance which controlled much of the trade in the eastern Mediterranean.

Antigonus I Monophthalmus was upset by this turn of events. In 305 BC he had his son Demetrius Poliorcetes, also a general, invade Rhodes with an army of 40,000; however, the city was well defended, and Demetrius—whose name "Poliorcetes" signifies the "besieger of cities"—had to start construction of a number of massive siege towers in order to gain access to the walls. The first was mounted on six ships, but these capsized in a storm before they could be used. He tried again with a larger, land-based tower named Helepolis, but the Rhodian defenders stopped this by flooding the land in front of the walls so that the rolling tower could not move.

In 304 BC a relief force of ships sent by Ptolemy arrived, and Demetrius's army abandoned the siege, leaving most of their siege equipment. To celebrate their victory, the Rhodians sold the equipment left behind for 300 talents (roughly US$360 million in today's money) and decided to use the money to build a colossal statue of their patron god, Helios. Construction was left to the direction of Chares, a native of Lindos in Rhodes, who had been involved with large-scale statues before. His teacher, the sculptor Lysippos, had constructed a 22 meter (70 ft) high bronze statue of Zeus at Tarentum.

3. Mausoleum of Maussollos >>>>

The Tomb of Mausolus, Mausoleum of Mausolus or Mausoleum at Halicarnassus (in Greek, Μαυσωλεῖον της Ἁλικαρνασσοῦ) was a tomb built between 353 and 350 BC at Halicarnassus (present Bodrum, Turkey) for Mausolus, a satrap in the Persian Empire, and Artemisia II of Caria, his wife and sister. The structure was designed by the Greek architects Satyrus and Pythius. It stood approximately 45 metres (135 ft) in height, and each of the four sides was adorned with sculptural reliefs created by each one of four Greek sculptors — Leochares, Bryaxis, Scopas of Paros and Timotheus. The finished structure was considered to be such an aesthetic triumph that Antipater of Sidon identified it as one of his Seven Wonders of the Ancient World.

In 623 BC, Halicarnassus was the capital of a small regional kingdom in the coast of Asia Minor. In 377 BC the ruler of the region, Hecatomnus of Milas, died and left the control of the kingdom to his son, Mausolus. Hecatomnus, a local satrap under the Persians, took control of several of the neighboring cities and districts. After Artemisia and Mausolus, he had several other daughters and sons: Ada (adopted mother of Alexander the Great), Idrieus and Pixodarus. Mausolus extended its territory as far as the southwest coast of Anatolia. Artemisia and Mausolus ruled from Halicarnassus over the surrounding territory for twenty-four years. Mausolus, although descended from local people, spoke Greek and admired the Greek way of life and government. He founded many cities of Greek design along the coast and encouraged Greek democratic traditions.

4. Temple of Artemis >>>>

The Temple of Artemis (Greek: Ἀρτεμίσιον Artemision, also known less precisely as Temple of Diana, was a Greek temple dedicated to Artemis completed— in its most famous phase— around 550 BC at Ephesus (in present-day Turkey) under the Achaemenid dynasty of the Persian Empire. Nothing remains of the temple, which was one of the Seven Wonders of the Ancient World. There were previous temples on its site, where evidence of a sanctuary dates as early as the Bronze Age.

The old temple antedated the Ionic immigration by many years. Callimachus, in his Hymn to Artemis, attributed the origin of the temenos at Ephesus to the Amazons, whose worship he imagines already centered upon an image (bretas). In the seventh century the old temple was destroyed by a flood. Around 550 BC, they started to build the "new" temple, known as one of the wonders of the ancient world. It was a 120-year project, initially designed and constructed by the Cretan architect Chersiphron and his son Metagenes, at the expense of Croesus of Lydia.

Artemis was a Greek goddess, the virginal huntress and twin of Apollo, who supplanted the Titan Selene as goddess of the Moon. Of the Olympian goddesses who inherited aspects of the Great Goddess of Crete, Athene was more honored than Artemis at Athens. At Ephesus, a goddess whom the Greeks associated with Artemis was passionately venerated in an archaic, certainly pre-Hellenic cult image that was carved of wood and kept decorated with jewelry. Robert Fleischer identified as decorations of the primitive xoanon the changeable features that since Minucius Felix and Jerome's Christian attacks on pagan popular religion had been read as many breasts or "eggs" — denoting her fertility. Most similar to Near-Eastern and Egyptian deities, and least similar to Greek ones, her body and legs are enclosed within a tapering pillar-like term, from which her feet protrude. On the coins minted at Ephesus, the apparently many-breasted goddess wears a mural crown (like a city's walls), an attribute of Cybele (see polos). On the coins she rests either arm on a staff formed of entwined serpents or of a stack of ouroboroi, the eternal serpent with its tail in its mouth. Something the Lady of Ephesus had in common with Cybele was that each was served by temple slave-women, or hierodules (hiero "holy", doule "female slave"), under the direction of a priestess who inherited her role, attended by a college of eunuch priests called "Megabyzoi" and also by young virgins (korai)

5. Statue of Zeus at Olympia >>>>

The Statue of Zeus at Olympia was one of the Seven Wonders of the Ancient World. It was made by the Greek sculptor of the Classical period, Phidias, circa 432 BC on the site where it was erected in the temple of Zeus, Olympia, Greece.

The seated statue, some 12 metres (39 feet) tall, occupied the whole width of the aisle of the temple built to house it. "It seems that if Zeus were to stand up," the geographer Strabo noted early in the first century BC, "he would unroof the temple." Zeus was a chryselephantine sculpture, made of ivory and gold-plated bronze. No copy, in marble or bronze, has survived, though there are recognizable but approximate versions on coins of Elis and Roman coins and engraved gems but a very detailed description of the sculpture and the throne was recorded by the traveller Pausanias, in the second century AD. In the sculpture, he was wreathed with shoots of olive and seated on a magnificent throne of cedarwood, inlaid with ivory, gold, ebony, and precious stones. In Zeus' right hand there was a small statue of crowned Nike, goddess of victory, also chryselephantine, and in his left hand, a sceptre inlaid with metals, on which an eagle perched.Plutarch, in his Life of the Roman general Aemilius Paulus, records that the victor over Macedon, when he beheld the statue, “was moved to his soul, as if he had beheld the god in person,” while the Greek orator Dio Chrysostom declared that a single glimpse of the statue would make a man forget his earthly troubles.

The date of the statue, in the third quarter of the fifth century BC, long a subject of debate, was confirmed archaeologically by the rediscovery and excavation of Phidias' workshop.

According to a legend, when Phidias was asked what inspired him -- whether he climbed Mount Olympus to see Zeus, or whether Zeus came down from Olympus so that Phidias could see him -- the artist answered that he portrayed Zeus according to Book One, verses 528 - 530 of Homer´s Iliad

6.Hanging Gardens of Babylon >>>>

The Hanging Gardens of Babylon, also known as the Hanging Gardens of Semiramis, near present-day Al Hillah in Iraq (formerly Babylon), is considered one of the original Seven Wonders of the World. They were built by Nebuchadnezzar II around 600 BCE. He is reported to have constructed the gardens to please his wife, Amytis of Media, who longed for the trees and fragrant plants of her homeland Persia.The gardens were destroyed by several earthquakes after the 2nd century BCE.

The lush Hanging Gardens are extensively documented by Greek historians such as Strabo and Diodorus Siculus. Through the ages, the location may have been confused with gardens that existed at Nineveh, since tablets from there clearly show gardens. Writings on these tablets describe the possible use of something similar to an Archimedes' screw as a process of raising the water to the required height

7.Great Pyramid of Giza >>>>

The Great Pyramid of Giza, also called Khufu's Pyramid or the Pyramid of Khufu, and Pyramid of Cheops, is the oldest and largest of the three pyramids in the Giza Necropolis bordering what is now Cairo, Egypt, and is the only remaining member of the Seven Wonders of the Ancient World. It is believed the pyramid was built as a tomb for Fourth dynasty Egyptian King Khufu (Cheops in Greek) and constructed over a 20 year period concluding around 2560 BC. The Great Pyramid was the tallest man-made structure in the world for over 3,800 years. Originally the Great Pyramid was covered by casing stones that formed a smooth outer surface, and what is seen today is the underlying core structure. Some of the casing stones that once covered the structure can still be seen around the base. There have been varying scientific and alternative theories regarding the Great Pyramid's construction techniques. Most accepted construction theories are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place.

There are three known chambers inside the Great Pyramid. The lowest chamber is cut into the bedrock upon which the pyramid was built and was unfinished. The so-called Queen's Chamber and King's Chamber are higher up within the pyramid structure. The Great Pyramid of Giza is the main part of a complex setting of buildings that included two mortuary temples in honor of Khufu (one close to the pyramid and one near the Nile), three smaller pyramids for Khufu's wives, an even smaller "satellite" pyramid, a raised causeway connecting the two temples, and small mastaba tombs surrounding the pyramid for nobles.
