Black Pyramid
Of all the Old and Middle Kingdom pyramids at Dahshur, the one built for Amenemhet III (1844–1797 BC) is, perhaps, the most easily recognizable. It was originally constructed out of black mud brick and encased with fine limestone that was later plundered, leaving it with the darker color that led to its modern-day name. It took an estimated 15 years to build this structure, which measures 31 square meters (344 square feet) and was originally 80 meters (265 feet) tall. Its pyramidion (a pyramid's crowning feature) was fashioned from black basalt and now resides in the Egyptian Museum.
Nearby are tombs belonging to other members of the court, unlikely to be open to the public. Like Sneferu, Amenemhet III had two pyramids; the other one is in Hawara in Fayyum.
