Of the Seven Wonders of the Ancient World, the only one that still exists today is the Great Pyramid of Giza. The pyramid was built as a tomb for the pharaoh Khufu (also called Cheops) during his reign from 2589 to 2566 BC. The pharaoh wanted his pyramid to be greater than any other. He succeeded beyond all expectations in scale, mystery, and awe.

The Great Pyramid is comprised of over 2.3 million individual limestone blocks, which weigh an average of 2.5 tons each. The Great Pyramid stands just over 455 feet or about 45 stories high, although it is notable that over the course of millennia, the structure has eroded almost 20 feet. In fact, the Great Pyramid was the tallest man-made structure from the time of its construction until the 14th century A.D.

As impressive as the outside of the Pyramid may be, the secrets of its interior architecture are just as fascinating with new mysteries constantly being discovered.

Main Entrance

The Main Entrance to the Great Pyramid is blocked up on the north face of the structure. In fact, it was hidden until 820 A.D. when the caliph Abdullah Al Mamun used men to bore into the structure, creating the Robber’s Tunnel. While they were excavating, they found the true entrance. It is through the Robber’s Tunnel that tourists enter the pyramid today. After a horizontal journey of approximately 90 feet, it finds the original interior passageways.
