Pyramids

Pyramids, structures built by the Egyptians and other ancient peoples as royal tombs or temples; they are composed of square bases and 4 triangular faces that meet at a common point, the apex. The Egyptian pyramids, erected around 4,500 years ago, are the largest and most notable. The first pyramid dates back to the Old Kingdom and was built by the architect Imhotep for King Zoser c.2650 B.C. The largest pyramid was constructed for King Khufu (reigned c.2589–c.2566 B.C.), also known as Cheops. It is 13 acres (5.3 hectares) in area and 482 ft (147 m) high. It is considered one of the Seven Wonders of the Ancient World. Pyramidal structures were also constructed by the native peoples of Central and South America. The Mayan pyramids were characterized by level tops that were probably used as pulpits.
