A symbol of Christianity, the statue has become an icon of Rio and Brazil.
2. The Great Wall of 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 farther 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.
Before the use of bricks, the Great Wall was mainly built from earth, stones, and wood. During the Ming Dynasty, however, bricks were heavily used in many areas of the wall, as were materials such as tiles, lime, and stone. The size and weight of the bricks made them easier to work with than earth and stone, so construction quickened. Additionally, bricks could bear more weight and endure better than rammed earth. Stone can hold under its own weight better than brick, but is more difficult to use. Consequently, stones cut in rectangular shapes were used for the foundation, inner and outer brims, and gateways of the wall. Battlements line the uppermost portion of the vast majority of the wall, with defensive gaps a little over 30 cm (a foot) tall, and about 23 cm (9 inches) wide.
The steps that form the Great Wall of China are very steep and tall in some areas. Tourists often become exhausted climbing the wall and walk no more than a kilometre or two (around a mile).
3. The Colosseum in Rome
The Colosseum or Coliseum, originally the Flavian Amphitheatre, is an elliptical amphitheatre in the centre 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 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.
Originally capable of seating around 50,000 spectators, the Colosseum was used for gladiatorial contests and public spectacles. It 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.
Although it is now in a ruined condition due to damage caused by earthquakes and stone-robbers, the Colosseum has long been seen as an iconic symbol of Imperial Rome. Today it is one of modern 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.
4. Petra in Jordan
Petra is an archaeological site in southwestern Jordan, lying on the slope of Mount Hor 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 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. It was famously described as "a rose-red city half as old as time" in a Newdigate prize-winning sonnet by John William Burgon. 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 designated as a UNESCO World Heritage Site in 1985 when it was described as "one of the most precious cultural properties of man's cultural heritage."
5. Machu Picchu in Peru
Machu Picchu (Quechua: Machu Pikchu "Old Peak") is a pre-Columbian Inca city located at 2,430 m (7,970 ft) altitude on a mountain ridge above the Urubamba Valley in Peru, about 70 km (44 mi) northwest of Cusco. Machu Picchu is probably the most familiar symbol of the Inca Empire. It is often referred to as "The Lost City of the Incas". The site was designated as a World Heritage Site in 1983 when it was described as "an absolute masterpiece of architecture and a unique testimony to the Inca civilization".
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.
6. Chichen Itza in Mexico
Chichen Itza is 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.
Archaeological data, such as evidence of burning at a number of important structures and architectural complexes, suggest that Chichen Itza's collapse was violent. Following the decline of Chichen Itza's hegemony, regional power in the Yucatán shifted to a new center at Mayapan.
According to the American Anthropological Association, the actual ruins of Chich'en Itza are federal property, and the site’s stewardship is maintained by Mexico’s National Institute of Anthropology and History (Instituto Nacional de Antropología e Historia, INAH). The land under the monuments, however, is privately-owned by the Barbachano family.
7. The Taj Mahal in India
The Taj Mahal, a mausoleum located in Agra, India was built under Mughal Emperor Shah Jahan in memory of his favorite wife, Mumtaz Mahal.
The Taj Mahal (also "the Taj") is considered as the finest example of Mughal architecture, a style that combines elements from Persian, Turkish, Indian, and Islamic architectural styles. In 1983, 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 most familiar, Taj Mahal is an integrated complex of structures and were completed around 1648. Ustad Ahmad Lahauri is generally considered as the principal designer of Taj Mahal.
