Egyptologists believe the pyramid was built as a tomb for the Fourth Dynasty Egyptian pharaoh Khufu and was constructed over a 20-year period. Khufu's vizier, Hermione, is believed by some to be the architect of the Great Pyramid. The Great Pyramid of Giza is the oldest and largest of the three pyramids in the Giza pyramid complex bordering present-day Giza in Greater Cairo, Egypt. It is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact.
