The Great Pyramid of Giza is the oldest and the largest of the three pyramids in the Giza necropolis bordering what is now Cairo, Egypt, in Africa. The three pyramids lie along with a sphinx. The oldest and the only remaining member of the Ancient Wonders, there is an abiding consensus on Giza's inclusion in the Wonders' list, and the monument does not require any description by historians and poets. It is believed to have been constructed over a 20-year period, concluding around 2560 BC.
