The Taj Mahal, INDIA

The Taj Mahal is located in Agra, India. The Mughal Emperor Shah Jahan build it for his favorite wife, Mumtaz Mahal. Construction began in 1632 and was completed in approximately 1648. Some dispute surrounds the question of who designed the Taj Mahal; it is clear a team of designers and craftsmen were responsible for the design, with Ustad Ahmad Lahauri considered the most likely candidate as the principal designer. The Taj Mahal is generally considered the finest example of Mughal architecture, a style that combines elements of Persian, Turkish, Indian, and Islamic architectural styles. While the white domed marble mausoleum is the most familiar part of the monument, the Taj Mahal is actually an integrated complex of structures. In 1983 the Taj 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."

Chichen Itza, MEXICO

Chichen Itza, a large pre-Columbian archaeological site built by the Maya civilization located in the northern center of the Yucatán Peninsula, present-day Mexico. Chichen Itza was a major regional center in the northern Maya lowlands from the Late Classic through the Terminal Classic and into the early portion of the Early Postclassic period.

The site exhibits a multitude of architectural styles, from what is called “Mexicanized” and reminiscent of styles seen in central Mexico to the Puuc style found among the Puuc Maya of the northern lowlands. The presence of central Mexican styles was once thought to have been representative of direct migration or even conquest from central Mexico, but most contemporary interpretations view the presence of these non-Maya styles more as the result of cultural diffusion.

The Great Wall of China, CHINA

The Great Wall of China 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 during the rule of successive dynasties. Several walls, referred to as the Great Wall of China, were built since the 5th century BC, the most famous being the one built between 220 BC and 200 BC by the first Emperor of China, Qin Shi Huang. That wall was much
further north than the current wall, built during the Ming Dynasty, and little of it remains.

The Great Wall is the world's longest human-made structure, stretching over approximately 6,400 km (4,000 miles) from Shanhai Pass in the east to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia. It is also the largest human-made structure ever built in terms of surface area and mass.

Machu Picchu, COLUMBIA

Machu Picchu (sometimes called the "Lost City") is a pre-Columbian city created by the Inca Empire. It is located at 2,430 m (7,970 ft) on a mountain ridge. Machu Picchu is located above the Urubamba Valley in Peru, about 70 km northwest of Cusco. Forgotten for centuries by the outside world, although not by locals, it was brought back to international attention by archaeologist Hiram Bingham in 1911, who made the first scientific confirmation of the site and wrote a best-selling work about it. Peru is pursuing legal efforts to retrieve thousands of artifacts that Bingham removed from the site.

'Petra', JORDAN

'Petra' is an archaeological site in Jordan, lying in a basin among the mountains which form the eastern flank of Arabah (Wadi Araba), the large valley running from the Dead Sea to the Gulf of Aqaba. It was famously described as "a rose-red city half as old as time". It is famous for having many stone structures carved into the rock. The long-hidden site was revealed to the Western world by the Swiss explorer Johann Ludwig Burckhardt in 1812. Burgon had not actually visited Petra; which remained accessible only to Europeans accompanied by local guides with armed escorts, until after World War I.

The site was inscripted as a United Nations Educational, Scientific and Cultural Organization World Heritage Site in 1985 when it was described as "one of the most precious cultural properties of man's cultural heritage.". Recently named one of the New Seven Wonders of the World.

The Colosseum, Rome, ITALY

The Colosseum or Coliseum is a giant amphitheatre in the centre of the city of Rome, Italy, having the capability of around 50,000 spectators, it was used for gladiatorial contests and public spectacles. Under the emperor Vespasian, it was built on a site just east of the Roman Forum, with construction starting between 70 and 72 AD. This amphitheatre was the largest ever built in the Roman Empire, was completed in 80 AD under Titus, with further modifications being made during Domitian's reign.

The Colosseum remained in use for nearly 500 years with the last recorded games being held there as late as the 6th century — well after the traditional date of the fall of Rome in 476. As well as the traditional gladiatorial games, many 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 eventually ceased to be used for entertainment in the early medieval era. It was later reused for such varied purposes as housing, workshops, quarters for a religious order, a fortress, a quarry and a Christian shrine.
