The largest pyramids were built by Khafre (Cheops) and his son Kefren (Chephren).

Khafre's pyramid stood 147 metres tall. Each side was 230 metres (with only 0.2% margin error - can you believe that?)

René's mum stands at the foot of Kefren's pyramid.

It is almost a one-kilometre walk around the whole pyramid.

It is taller than Kefren's pyramid but does not look so as it sits on lower ground.
It is estimated that something like 2.3 million blocks were used to build the pyramid.

Right: There once lay a solar-boat. Khafre's mummy was placed into this boat as the ancient Egyptians believed the pharaoh sailed to the after-life.
The boat is now housed in a building next to the pyramid.
