Among the Seven Wonders of the Ancient World, the oldest one is the Great Pyramid of Giza. There are three large pyramids at Giza, outside the modern capital of Egypt, Cairo. The largest and most famous one is called the Great Pyramid. The workers built it as a tomb (坟墓) for the Pharaoh Khufu (法老胡夫).

It took more than twenty years to build the Great Pyramid. When it was built, the pyramid was about 146.5 metres high. Over the years it has lost about eight metres off its top.

The pyramid is made of large stone blocks (石块) — 2,300,000 of them! Each of these blocks weighs over 2,000 kilograms. The ancient Egyptians did not have any modern machines. How did they build the pyramid? The pyramid shows that the ancient people were intelligent and had great skills.

People once thought that the Egyptians made slaves (奴隶) do all the work on the Great Pyramid. But in fact, they used farmers.
