An entrance grave is a roughly round cairn of stones and soil, of prehistoric date, revetted by a kerb of boulders, covering a rectangular-shaped chamber. The chamber, which is usually of orthostatic construction, occupies much of the central portion of the cairn, and was accessible from the outside of the cairn though a gap in the kerb.
Although generally distinctive as field monuments, some specimens may be confused with certain classes of round barrow, especially bowl barrows.Without excavation it can be very difficult to distinguish between examples of these two otherwise distinct classes.
Entrance graves were constructed as burial monuments.
