The Great Pyramid of Giza (also called the Pyramid of Khufu and the Pyramid of Cheops) is the oldest and The largest pyramid in the world, built almost 4,600 years ago. It’s made up of 2,300,000 blocks, with the average weight of 2.5 tons. Some stones weigh up to 15 tons. It was originally 146.5 metres high (before the casing stones were removed), and 230 metres along the base.
It is believed the pyramid was built as a tomb for and named after Khufu who was a pharaoh of the 4th Dynasty and ruled for 24 years, from 2589 until 2566 BCE.
The pyramid was constructed over a 20-year period concluding around 2551 BC.
The general belief is that it was built by moving huge stones from a quarry and dragging and lifting them into place.
The pyramid consists of 3 chambers (found so far). The lowest chamber is cut into the bedrock upon which the pyramid was built and was unfinished. The Queen’s Chamber and King’s Chamber are higher up within the pyramid structure. The Great Pyramid of Giza is the main part of a complex setting of buildings that included two mortuary temples in honor of Khufu (one close to the pyramid and one near the Nile), three smaller pyramids for Khufu’s wives, an even smaller “satellite” pyramid, a raised causeway connecting the two temples, and small mastaba tombs surrounding the pyramid for nobles.
The pyramid is the oldest of the Seven Wonders of the Ancient World and the only one to survive substantially intact.
