Great Pyramid of Giza
The Great Pyramid of Giza is the oldest and largest of the three pyramids in the Giza pyramid complex, built as a tomb for the Egyptian pharaoh Khufu and the only surviving structure of the ancient Seven Wonders of the World.
Built around 2560 BCE, the pyramid originally stood at 481 feet, making it the tallest man-made structure in the world for nearly 3,800 years. It is estimated to be built from over 2 million limestone and granite blocks.
The precise methods used to construct the pyramid remain a subject of study and debate among archaeologists, though most agree it involved a rotating labor force of skilled workers rather than enslaved laborers, as long assumed.
Today the pyramid is part of the Giza Necropolis, a UNESCO World Heritage Site, and remains one of the most studied and visited ancient structures on Earth.
