Amenemhet’s pyramid, as usual for the pyramid was built of mud brick and cased with limestone. the pyramid was built with a base length of 105 m and a height of 58 m rising with a slope of 48 o 45 o as the king built another pyramid in dahshur which had been abandoned because it’s lack of suitability so the fear of collapse probably what caused the builders of the Hawara pyramid to lower the slope with as much as 9o 30o.
The pyramid’s core was built entirely of mud brick stones with only an outer in limestone. The limestone encasing has been pillaged by stone robber’s centuries ago but the limestone core still remains, giving the modern visitor the impression of Amudbrick Mountain.
