The Pyramids, Egypt

Two thousand feet above the Urubamba river, these ruins consist of baths, temples, palaces, and about 150 houses, all very well preserved. These gray granite structures, some of which weigh more than 50 tons, are so perfectly sculpted that they are nothing less than works of architectural genius. They were rediscovered by a Yale archaeologist in 1911. The ethereal beauty, workmanship, and history of the place attracts millions of tourists each year.

The Pyramids, Egypt

The Egyptian pyramids are massive monuments with a square base and four triangular sides rising up to a point. There is still a lot of curiosity (and many theories) as to how the pyramids were actually constructed.
