| Believe it or not, ancient ruins are very popular 
		among tourists. They are one of the few ways modern man can come into 
		contact with the wonders of ancient technology and art and travel back 
		to times long past. Here a look at the worlds most famous ancient ruins:

		| 
		Great Wall, Badaling, China
 With a name so simple, yet so powerful, the Great Wall stretches for 
		5,500 miles across China. Its most beautiful section is also easily 
		accessible — within 70 miles of Beijing. While much of what is visible 
		today was built during the Ming Dynasty (1368 to 1644), construction 
		began on various sections as far back as 770 BC. Annual visitors: 9 to 
		10 million.

		Terracotta Army, Xi’an, China
 
 Discovered in 1974, these 700 life-size terracotta generals, 
		infantrymen, archers and chariot drivers are each unique, with distinct 
		facial features, hairstyles and clothing. The clay statues were arranged 
		in rows in covered pits as part of a necropolis for Emperor Qin Shi 
		Huang. More are believed to still be buried, but work on removing and 
		restoring the soldiers has been halted until a way can to found to keep 
		their bright paint from fading in the air. Annual visitors: 3.6 to 4.5 
		million.

		Pyramids of Giza, Egypt
 As one of the original Seven Wonders of the World and certainly the 
		symbol of Egypt, the Pyramids have been venerated for 4,500 years. But 
		how the ancient Egyptians built them is unknown, which adds to their 
		intriguing appeal. The three major tombs for pharaohs that rest at this 
		Unesco World Heritage Site are now surrounded on three sides by the 
		pressures of Cairo, a city teeming with nearly 11 million people. Annual 
		visitors: four million.

		Roman Forum, Rome
 The social centre of Rome for 1,200 years beginning in the 5th Century 
		BC, this 700-yard-long piazza has been both a marketplace and a 
		government centre. The ruins of sacred temples’ columns and friezes 
		(whether dedicated to Saturn, the god of agriculture, or to the emperors 
		Vespasian and Titus) hint at the Forum’s level of grandeur two millennia 
		ago. Annual visitors: 5.1 million.

		Colosseum, Rome
 When completed in 80 AD, the arena held 50,000 spectators who watched 
		mythical dramas, re-enactments of land and sea battles, executions, 
		fights-to-the-death and the ghastly slaughter of wild animals. The 
		underground pits where gladiators awaited their fates were opened to 
		visitors in 2010, along with the 110ft-high upper ring of seats, which 
		offer panoramic views of the Eternal City. Annual visitors: 6.9 million.
