This royal tomb, which the Pharaoh's soul climbed to reach the afterlife, is testament to the genius of Imhotep. The pyramid is made up of six levels of mastabas piled one on top of the other in a remarkable architectural feat. It is also one of the oldest pyramids in the world. The royal apartments and tomb (28m and 33m deep respectively), are accessed via a maze of galleries dug straight out of the rock. A series of digs have resulted in thousands of objects being discovered at the pyramid.
