The history of this site is a somewhat shorter than the history of its northern neighbour, Saqqara. Archaeological research has revealed no traces of activity in this area before Snofru, which may mean that Snofru chose this area, among others, because it had not been used before. A similar motivation may have driven him to found the royal necropolis at Meidum, some 15 years earlier. It is, however, not known why he abandoned Meidum to favour a new virgin site. Some have speculated that Snofru wanted to be closer to the Nile Delta, but if that really were the case, one could wonder why he did not move to an even more northern site such as Giza or Abusir.

Perhaps the explanation might be found in the fact that at Dashur Snofru did not build a Step Pyramid, as he had done in Meidum, but a true pyramid. The shift from Step Pyramid to true pyramid represents a shift in ideology, turning from a royal tomb that represented a staircase to the stars to a monument that was both a solar symbol and a reference to the primeval mound from which all life had supposedly sprung.

Perhaps because the change of angle did not conform to the new ideology, Snofru started a second pyramid,
