The mastaba next to the pyramid of Snefru is one of the most impressive of all of Egypt. It is a superstructure, perhaps recreating a holy mountain or a raised underground, containing numerous independent graves. Later mastabas were individual graves. Its wall are more slanting than usual with mastabas. The only mastaba of a measurable scale, the Mastaba of al-Faraoun in South Saqqara, has near-vertical walls. The slanting walls may have been a reflection of the shape of the pyramid.
