A tumulus (plural tumuli) is a mound of earth and stones raised over a grave site. The word tumulus is Latin for 'mound' or 'small hill'.
Tumuli are also known as barrows, burial mounds, Hügelgrab or kurgans, and can be found throughout much of the world. A tumulus composed largely or entirely of stones is usually referred to as a cairn. A long barrow is a long tumulus, usually for numbers of burials.
The method of inhumation may involve a dolmen, a cist, a mortuary enclosure, a mortuary house or a chamber tomb.
