The entrance to the subterranean structures lies on the east, a disposition which would be unparalleled until the construction of the pyramid of Senusret II, almost 1000 years later. The egyptologists Vito Maraglioglio and Celeste Rinaldi proposed that this unique feature was chosen by the Egyptian architects in order to free the north side of the pyramid for the construction of a temple.[11] Aidan Dodson showed however that in this situation, the pyramid construction ramp would have "impinged on any northern temple construction even more damagingly". Rather, he explains this unique eastern entrance as resulting from a desire by the architects to allow for easy access to the pyramid store rooms, located immediately beneath the eastern entrance.[2]
