A royal necropolis in Egypt's southeastern Al-Fayyum region, known as the site of the second pyramid of King Amenemhat III (reigned 1818-1770 BC). The pyramid is dated to c 1844-1797 BC and it has a very large mortuary temple attached. Amenemhat III brought economic prosperity by building a system to regulate the inflow of water into Lake Moeris. As part of this great work, the labyrinth described by the Greek historian Herodotus was probably built nearby. Amenemhet erected two colossuses of himself nearby, also described by the Greek historian Herodotus.
