A pond barrow is a burial mound, circular in shape, well formed, and with an embanked rim made of the earth taken from the depression made in the ground.
In the barrow's centre there is generally a pit or shaft, sometimes containing a burial, sometimes of great depth. The barrows range from 5m to 30m (16.5 – 100 ft) in diameter. They are usually difficult to recognise, as time has rendered them less and less visible.
