Dashur: Black Pyramid of Amenemhat III. The Black Pyramid of Dashur was the first pyramid built by Amenemhat III (of the Middle Kingdom of Ancient Egypt) during the early part of his reign. Unfortunately the pharaoh failed to heard the warnings of history and so this pyramid is now in a rather poor state.
Early Egyptian kings were buried in mounds called mastabas. In approximately 2780 BC the first Egyptian pyramid was built as the burial chamber for King Djoser. Located at Sakkara near Memphis, Djoser's burial chamber was a step pyramid. According to the Smithsonian Museum the first smooth-sided pyramid was built during the reign of King Snefru, sometime between 2680-2560 BC. Snefru's son, Khufu, is responsible for building the most famous of all the pyramids, the Great Pyramid at Giza.
