A mausoleum (plural: mausolea) is a large and impressive tomb,
usually constructed for a deceased leader. Mausoleum can also refer
to a building which contains a number of crypts for entombment of
deceased individuals.

Modern mausolea will often have columbarium niches for cremated
remains in addition to traditional masoleum crypts. Mausolea can be
freestanding buildings, or can be part of a larger facility - such
as a church. The Cathedral of Our Lady of the Angels in Los Angeles,
California, for example, has 6,000 mausoleum and columbarium spaces
for burial in the lower level of the building.

The word came from the Mausoleum of Maussollos (near modern-day
Bodrum, Turkey), the grave of King Mausolus, the Persian satrap of
Caria, whose large tomb was one of the Seven Wonders of the Ancient
World.

In New York City, Grant's Tomb is a reduced-scale version of
Mausollos' monument. Other mausoleums include Abraham Lincoln's tomb
in Springfield, Illinois.
