The Great Pyramid of Giza (also called the Pyramid of Khufu and the Pyramid of Cheops) is the oldest and largest of the three pyramids in the Giza Necropolis bordering what is now El Giza, Egypt. It is the oldest of the Seven Wonders of the Ancient World and the only one to survive substantially intact. It is believed the pyramid was built as a tomb for fourth dynasty Egyptian Pharaoh Khufu (Cheops in Greek) and constructed over a 20-year period concluding around 2551 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; 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 hypotheses are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place.
2. The Colosseum or Roman Coliseum
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 considered 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[1] under the emperor Vespasian and was completed in 80 AD under Titus, with further modifications being made during Domitian's reign (81–96).[3] The name "Amphitheatrum Flavium" derives from both Vespasian's and Titus's family name (Flavius, from the gens Flavia).
Capable of seating 50,000 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[who?] 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 because of 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 that starts in the area around the Colosseum.
3.The 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: Wànli Chángchéng; literally "The long wall of 10,000 Li (?)"[1]) is a series of stone and earthen fortifications in northern China, built, rebuilt, and maintained between the 5th century BC and the 16th century to protect the northern borders of the Chinese Empire. Since the 5th century BC, several walls have been built that were referred to as the Great Wall. One of the most famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang. Little of that wall remains; the majority of the existing wall were built during the Ming Dynasty.
The Great Wall stretches from Shanhaiguan in the east to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia. The most comprehensive archaeological survey, using advanced technologies, has recently concluded that the entire Great Wall, with all of its branches, stretches for 8,851.8 km (5,500.3 mi). This is made up of 6,259.6 km (3,889.5 mi) of sections of actual wall, 359.7 km (223.5 mi) of trenches and 2,232.5 km (1,387.2 mi) of natural defensive barriers such as hills and rivers.
4. Hagia Sophia
Hagia Sophia is a former Orthodox patriarchal basilica, later a mosque, now a museum in Istanbul, Turkey. From the date of its dedication in 360 until 1453, it served as the cathedral of Constantinople except between 1204 and 1261, when it was the cathedral of the Latin empire. The building was a mosque from 23 May 1453 until 1934, when it was secularized; it was opened as a museum on 1 February 1935.
Famous in particular for its massive dome, it is considered the epitome of Byzantine architecture and to have "changed the history of architecture." It was the largest cathedral 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 532 and 537 A.D. 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 Isidore of Miletus, a physicist, and Anthemius of Tralles, a mathematician.
The church contained a large collection of holy relics and featured, among other things, a 15 metre (49 foot) silver iconostasis. It was the seat of the Patriarch of Constantinople and the religious focal point of the Eastern Orthodox Church for nearly one thousand years. It was the church in which Cardinal Humbert in 1054 marched up to the altar and excommunicated Michael I Cerularius, which is commonly considered the start of the Great Schism.
In 1453, Constantinople was conquered by the Ottoman Turks and Sultan Mehmed II ordered the building to be converted into a mosque.[4] 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 Sehzade Mosque, the Süleymaniye Mosque, the Rüstem Pasha Mosque, and the Kiliç Ali Pasa Mosque.
5. The Taj Mahal
The Taj Mahal 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, Indian, and Islamic architectural styles.[1][2] 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.[3] The construction of the Taj Mahal was entrusted to a board of architects under imperial supervision including Abd ul-Karim Ma'mur Khan, Makramat Khan, and Ustad Ahmad Lahauri.[4][5] Lahauri is generally considered to be the principal designer.
6. The Golden Gate Bridge
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the opening of the San Francisco Bay into the Pacific Ocean. As part of both U.S. Route 101 and California 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 was the longest suspension bridge span in the world when it was completed during the year 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 1999, it was ranked fifth on the List of America's Favorite Architecture by the American Institute of Architects.
7. Chichen Itza
Chichen Itza from Yucatec Maya: Chi'ch'èen Ìitsha', "At the mouth of the well of the Itza") is a large pre-Columbian archaeological site built by the Maya civilization located in the northern center of the Yucatán Peninsula, in the Yucatán state, present-day Mexico.
Chichen Itza was a major focal point 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 ruins of Chichen Itza are federal property, and the site’s stewardship is maintained by Mexico’s Instituto Nacional de Antropología e Historia (National Institute of Anthropology and History, INAH). The land under the monuments, however, is privately-owned by the Barbachano family.
8. The Grand Canyon
The Grand Canyon (Spanish: Gran Cañón) is a steep-sided gorge carved by the Colorado River in the United States in the state of Arizona. It is largely contained within the Grand Canyon National Park, one of the first national parks in the United States. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery.
The Grand Canyon is 277 miles (446 km) long, ranges in width from 4 to 18 miles (6.4 to 29 km) and attains a depth of over a mile (1.83 km) (6000 feet).[1] Nearly two billion years of the Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. While the specific geologic processes and timing that formed the Grand Canyon are the subject of debate by geologists,[3] recent evidence suggests the Colorado River established its course through the canyon at least 17 million years ago.[4] Since that time, the Colorado River continued to erode and form the canyon to the point we see it as today.
Before European immigration, the area was inhabited by Native Americans who built settlements within the canyon and its many caves. The Pueblo people considered the Grand Canyon ("Ongtupqa" in Hopi language) a holy site and made pilgrimages to it.[6] The first European known to have viewed the Grand Canyon was García López de Cárdenas from Spain, who arrived in 1540.
9. Machu Picchu
Machu Picchu is a pre-Columbian Inca site located 2,430 metres (7,970 ft) above sea level.[1] It is situated on a mountain ridge above the Urubamba Valley in Peru, which is 80 kilometres (50 mi) northwest of Cuzco and through which the Urubamba River flows. Most archaeologists believe that Machu Picchu was built as an estate for the Inca emperor Pachacuti (1438–1472). Often referred to as "The Lost City of the Incas", it is perhaps the most familiar icon of the Inca World.
The Incas started building the estate around AD 1400 but it was abandoned as an official site for the Inca rulers a century later at the time of the Spanish conquest of the Inca Empire. Although known locally, it was unknown to the outside world before being brought to international attention in 1911 by the American historian Hiram Bingham. Since then, Machu Picchu has become an important tourist attraction.
Machu Picchu was declared a Peruvian Historical Sanctuary in 1981 and a UNESCO World Heritage Site in 1983.[1] Since it was not plundered by the Spanish when they conquered the Incas, it is especially important as a cultural site and is considered a sacred place. Machu Piccu was named one of the New Seven Wonders of the World through an online and telephone poll conducted by the New7Wonders foundation.
Machu Picchu was built in the classical Inca style, with polished dry-stone walls. Its primary buildings are the Intihuatana, the Temple of the Sun, and the Room of the Three Windows. These are located in what is known by archaeologists as the Sacred District of Machu Picchu. In September 2007, Peru and Yale University reached an agreement regarding the return of artifacts which Hiram Bingham had removed from Machu Picchu in the early twentieth century.
