The Bent Pyramid is unique for two reasons. The first is the angle change. There are two theories for this change. The first is that the builders may have gotten tired and wanted to reduce the volume and to finish faster. Another is that when the pyramid at Maidoun collapsed, the architect lost his nerve and changed the angle. The angle at Maidoun was 52 degrees as is the base of the Bent Pyramid. At the bend, the angle is changed to 43.5 degrees up to the peak.
The second reason is that it has two entrances. The first is in the middle of the northern side and is about 12m above the ground. It leads to the upper chamber. The second entrance is on the western side and is just above the ground. It leads to the lower chamber. The floors of both chambers were built 4m deep with small stone blocks.
The Red Pyramid, the first successful attempt to build a true pyramid.
Sakkara is best known for the Step Pyramid, the oldest known of Egypt’s 97 pyramids.
It was built for King Zoser, one of the greatest Kings of the third dynasty (2721-2780 BC). Originally meant as a tomb, this Pyramid was designed and built by his great architect Imhotep. The Pyramid is built as a step Pyramid, 60m high, and consisting of 6 steps; each one built on top of each other and smaller than the one below.
