Dahshour was a main breeding ground for the pyramid age. Here we find several pyramids, including two Old Kingdom pyramids both unique, and both a distinct phase in the evolution of pyramid building and the pyramid complex.
King Sneferu (about 2600-2450) father of Khufu, was the curious builder of these pyramids, The Bent Pyramid earned its name from its distinct change in angle. The pyramid was began at an angle of 52 degrees and midway through its construction this angle was suddenly and still inexplicably changes to the safer angle of 43 degrees. this change in angle in the Bent pyramid would come for a different reason. Whatever the reason is, King Sneferu began a second pyramid at Dahshour, north of this first pyramid. This second pyramid, now called the Northern or Red Pyramid, was completely built at the angle of 43 degrees, as with the top portion of the Bent Pyramid.
