The earliest smooth-sided pyramid, located at Meidum, started out as a step pyramid under Huni structure. Sneferu's own later monuments, the Bent Pyramid and Red Pyramid at Dahshur, were the first true pyramids to be built as such from scratch, and it was with this innovation that the age of Egyptian stepped pyramids came to an end.
