Editing Bent Pyramid (section)

==Interior passages==
[[File:Bent Pyramid substructure 2.png|thumb|Showing the two entrances into the bent pyramid]]
The Bent Pyramid has two entrances, one fairly low down on the north side, to which a substantial wooden stairway has been built for the convenience of tourists. The second entrance is high on the west face of the pyramid. Each entrance leads to a chamber with a high, [[Corbel arch|corbelled roof]]; the northern entrance leads to a chamber that is below ground level, the western to a chamber built in the body of the pyramid itself. A hole in the roof of the northern chamber (accessed today by a high and rickety ladder {{convert|15|m|abbr=on|-1}} long) leads via a rough connecting passage to the passage from the western entrance.

The western entrance passage is blocked by two stone blocks which were not lowered vertically, as in other pyramids, but slid down 45° ramps to block the passage. One of these was lowered in antiquity and a hole has been cut through it, the other remains propped up by a piece of ancient cedar wood. The connecting passage referenced above enters the passage between the two portcullises.

A particular feature in the chambers are a row of original cedar beams that were interpreted by many as a reaction on structural problems. In contradiction to that, Edwards argues the cedar beams rather had been part of the funerary support structure and, some of them bedded in mortar, could not have any structural function.<ref>Edwards, LES, The Egyptian Pyramids, Harmondsworth 1947, page 93.</ref>
