The Great Pyramid of Giza was the first of the pyramids to be built on the Giza Plateau. It was built as a tomb for the ancient Egyptian pharaoh Khufu over a period of around 27 years. It is believed that Khufu's cousin and vizier, Hemiunu was the architect of the Great Pyramid.
Construction of the Great Pyramid was completed around 2560 BC, and it was the tallest man-made structure in the world for over 3,800 years.
