Teotihuacan

The Pyramid of the Sun (top) is the largest structure in the ancient city of Teotihuacan, Mexico, and one of the largest buildings of its kind on the Western Hemisphere. It stands 216 feet (66 meters) tall and measures 720 feet (220 meters) in width at its base.
Originally built as a smaller structure around A.D. 200, the pyramid was added to several times before it reached its current dimensions. It stands over a network of caves and tunnels, which archaeologists think were spiritually significant to the mysterious builders of Teotihuacan.

Siva Linga

A Siva Linga stands amid the ornate walls of the Angkor Wat temple in Cambodia. These short, cylindrical pillars are worshipped throughout the Hindu world as symbols of the god Shiva.

Peruvian Mummy

This well-preserved mummy was removed from an ancient Inca cemetery located just outside Peru's capital, Lima. The site, adjacent to Puruchuco-Huaqueron es, the largest Inca cemetery ever found, yielded dozens of human remains and artifacts dating back more than 500 years. The mummies were bundled in textile cocoons containing one or more adults or children

Terra-Cotta Warriors Tomb

Platoons of clay soldiers were buried with China's first emperor, Qin Shi Huang Di, to accompany him during his eternal rest. These life-size figures, shown here during excavation at the emperor's burial complex near the city of Xi'an in China's Shaanxi Province, are more than 2,200 years old.
The tomb, which extends over 22 square miles (57 square kilometers) and is said to have required a labor force of 700,000 to build, was discovered by a group of peasants digging a well in 1974.

Valley of the Kings, Egypt

The Pyramids of Giza and the Nile Delta were the tombs of choice for pharaohs of Egypt's Old Kingdom. But New Kingdom pharaohs, seeking to foil tomb raiders and be closer to the source of their dynastic roots in southern Egypt, created what's known now as the Valley of the Kings.
Deep inside the hills of this otherwise barren valley west of Luxor (seen here from above) sit the tombs of nearly all the pharaohs who ruled between 1539 and 1078 B.C. Their strategy in the end did not confound thieves, though, and almost all of the tombs had been ransacked by the time archaeologists began excavating the site in the early 1800s.
