The famous Pyramids of Giza are found in Cairo, Egypt.
There are three main pyramids at Giza: The Great Pyramid of Khufu, the Pyramid of Kafhre, and the Pyramid of Menkaura. Each pyramid is a tomb for an ancient Egyptian King.
The Giza pyramids were built around 5,000 years ago. It is believed about 20,000 workers were used just to build the Great Pyramid of Khufu. They used 2 million blocks of stone weighing 2.5 tons each.
The Great Pyramid is the last surviving wonder of the original Seven Ancient Wonders of the World. The list of Wonders includes now-destroyed sites like the Hanging Gardens of Babylon and the Colossus of Rhodes in Greece.
