Which Egyptian monument consists of three main pyramids and is a World Heritage Site?

The Pyramids of Giza are the Egyptian monument complex consisting of three main pyramids and included within a World Heritage Site.

The three principal pyramids are the Great Pyramid of Khufu, the Pyramid of Khafre, and the Pyramid of Menkaure. They were built during Egypt’s Fourth Dynasty in the Old Kingdom, when Giza served as a major royal burial area near the ancient capital of Memphis. Each pyramid formed part of a larger funerary complex with temples, causeways, cemeteries, and subsidiary pyramids.

The Great Pyramid was built for Khufu and was the tallest human-made structure in the world for thousands of years. Khafre’s pyramid appears taller from some viewpoints because it stands on higher ground and retains some casing stones near its summit. Menkaure’s pyramid is the smallest of the three. The nearby Great Sphinx is associated with the complex but is not itself one of the pyramids.

The Giza complex forms part of the UNESCO property called Memphis and its Necropolis: the Pyramid Fields from Giza to Dahshur, inscribed in 1979. The Great Pyramid is also the only surviving wonder of the ancient world.
