The ancient structure in Egypt that was built as a tomb for pharaohs is known as a pyramid, with the Great Pyramid of Giza being the most famous. Constructed around 2580–2560 BC, it served as the burial site for Pharaoh Khufu. The Great Pyramid is a monumental feat of engineering, originally standing at about 481 feet tall and consisting of approximately 2.3 million stone blocks. The pyramids not only symbolize the power of the pharaohs but also reflect their beliefs in the afterlife, as they were designed to protect the tombs and enable a smooth passage to the next world.
