Pyramid of Nyuserre.
The Pyramid of Nyuserre is a pyramid complex built in the 25th century BC for the Egyptian pharaoh Nyuserre Ini of the Fifth Dynasty. It is in the Abusir necropolis south of modern-day Cairo between the complexes of Neferirkare and of Sahure. Nyuserre was the last king to be entombed in the necropolis. The main pyramid, nearly 52 m (171 ft) tall, had a stepped core built from roughly cut limestone encased in fine Tura limestone. The casing was stripped by stone thieves, leaving the core exposed to the elements and further human activity, reducing the pyramid to a ruined mound. Adjoining the pyramid's east face is the mortuary temple built in an L-shape rather than the usual T-shape plan. It introduced the antichambre carrée, an innovative type of room that became a standard feature of later monuments. The site has two structures which appear to have been pylon prototypes. These, too, became staple features of temples and palaces in a later period.
