Meidum or Maidum is the location of a large pyramid, and several large mud-brick mastabas. It is located about 62 miles (100 km) south of modern Cairo.
The pyramid at Meidum is thought to originally have been built for Huni, the last pharaoh of the Third Dynasty, and was continued by Sneferu. The architect was a successor to the famous Imhotep, the inventor of the stone built pyramid. The collapse of the pyramid is likely due to the modifications made to Imhotep’s pyramid design as well as the decisions taken twice during construction to extend the pyramid. Because of its unusual appearance, the pyramid is called el-heram el-kaddaab — (Pseudo Pyramid) in Egyptian Arabic.
