The current ruined state of the pyramid allows a view of its core, which is a 11 m2 (120 sq ft) pyramidal mound made of poor quality rough stone blocks taken from the local bedrock.[2] This core is surrounded by a 2.6 m (8.5 ft) thick casing of the same masonry. This is in turn surrounded by 14 layers of mud bricks bonded with clay mortar and disposed almost vertically,[6] with an inward inclination angle of 68°. Just as the inner-most stone casing of the pyramid core, each mud brick layer is 2.6 m (8.5 ft) thick.[3][4]
