Of the three Middle Kingdom pyramid complexes built by Amenemhat II (1922-1878 BC), Sesostris III (1874-1855 BC) and his son Amenemhat III (1855-1808 BC), only the oddly shaped Black Pyramid of Amenemhat III is worth a look. The towerlike structure appears to have completely collapsed due to the pilfering of its limestone outer casing in medieval times, but the mud-brick remains contain a maze of corridors and rooms designed to deceive tomb robbers.

Thieves did manage to penetrate the burial chambers, but left behind a number of precious funerary artefacts that were discovered in 1993.
