The Bent Pyramid was probably the first planned from the outset to be a true pyramid, with smooth sides. It is the most unusual pyramid because of the fact that during its construction Egyptians changed its angle. Perhaps because of the awkward angles in the Bent Pyramid, Snefru ordered another pyramid to be built nearby – the Red Pyramid that we will have a chance to enter. It is an elegant precursor to the Great Pyramids at Giza.
