The Great Pyramid of Giza is a giant pyramid built by the Ancient Egyptians. It stands close to Cairo, Egypt. It is the oldest of the Seven Wonders of the Ancient World, and it's the only one that is still mostly complete. When it was built, it was 146.5 meters (481 feet) tall. It was the tallest building in the world for more than 3,800 years!

The pyramid was built for Khufu, an Egyptian pharaoh (king). Some people believe Khufu's helper, Hemiunu, was the main builder. It probably took about 20 years to build and was finished around 2570 BC.
