Bent Pyramid

The Bent Pyramid located at Dahshur was the second pyramid built by pharaoh Sneferu. Mysteriously, the pyramid rises from the desert at an angle of 55 degrees and then suddenly changes to a more gradual angle of 43 degrees. One theory holds that due to the steepness of the original angle the weight to be added above the inner chambers and passageways became to large, forcing the builders to adopt a shallower angle. It is the only pyramid in Egypt of which the outer casing of polished limestone is still largely intact.
