A dolmen or portal tomb is a type of single-chamber megalithic tomb, usually consisting of two or more upright megaliths supporting a large flat horizontal capstone or "table". Most date from the Late Neolithic period and were sometimes covered with earth or smaller stones to form a tumulus. Small pad-stones may be wedged between the cap and supporting stones to achieve a level appearance. In many instances, the covering has eroded away, leaving only the stone "skeleton".
A tumulus is a mound of earth and stones raised over a grave or graves. Tumuli are also known as barrows, burial mounds or kurgans, and may be found throughout much of the world. A cairn, which is a mound of stones built for various purposes, may also originally have been a tumulus.
Entrance grave is a type of Neolithic and early Bronze Age chamber tomb found primarily in Great Britain. The burial monument typically consisted of a circular mound bordered by a stone curb, erected over a rectangular burial chamber and accessed by a narrow, stone lined entrance. Entrance graves have been discovered in the Isles of Scilly, west Cornwall, southeast Ireland, southwest Scotland, Brittany and the Channel Islands. They are often referred to as the Scillonian Group, named for the Scillonian Islands where the majority of entrance graves have been discovered.
