A beehive tomb, also known as a tholos tomb, is a burial structure characterized by its false dome created by corbelling, the superposition of successively smaller rings of mudbricks or, more often, stones. The resulting structure resembles a beehive, hence the traditional English name.

A dome is an architectural element similar to the hollow upper half of a sphere. There is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome. The precise definition of a dome has been a matter of controversy and there are a wide variety of forms and specialized terms to describe them.
