The most famous pyramids are those used as mausolea in ancient Egypt; they were focal points of much larger funerary complexes. However, pyramids, usually with flat tops, are also found in Central America, where they were used as platforms for altars or temples, occasionally also covering the burial chamber of a ruler. ]]></note></mads>
