What are the Pyramids of Giza?
In the desert outside Cairo, three enormous stone mountains rise from the sand — perfect triangles that have stood for more than four thousand years. They're not natural hills. They're tombs, built by hand, one block at a time, for three ancient Egyptian kings.
The biggest one, the Great Pyramid, was built for King Khufu around 2560 BCE. It's made of more than two million limestone blocks, each one weighing as much as a car. The whole thing was originally covered in smooth white limestone that gleamed like a mirror in the sun.
