A mausoleum is a building that contains a tomb or tombs. The Taj Mahal, built by Shah Jahan as a monument to his third wife, Mumtaz Mahal, is the world's most famous mausoleum.
Mausoleion, the Greek source of the Latinized mausoleum, was the name given to the tomb of the King Mausolus, a Persian ruler who died in 353 B.C.E. This vast elaborate structure was one of the Seven Wonders of the Ancient World. Other notable mausoleums or mausolea include the mausoleum of China's First Qin Emperor –- the site of the famous Terra Cotta Army — and the tombs of Ulysses S. Grant and Abraham Lincoln.
