This circular, drystone structure lies on top of a Bronze Age burial cairn NPRN 303533. Within the centre of the structure is a concrete Ordnance Survey triangulation pillar but probably not associated with it. The structure has a continuous wall with no entrance. It is approximately 4 metres in diameter and the walls stand up to 0.8 metres high. J.J. Hall, Trysor, 15 July 2012
