It is the kind of place you could walk past without registering, yet what lies on top of it is a passage tomb, a Neolithic burial monument in which the dead were interred within a stone chamber reached by a narrow stone-lined corridor. The mound itself is roughly 30 to 35 metres across and rises about 1.7 metres on its southern side, enough to give it a faint but deliberate presence in otherwise level ground. The Ox Mountains trace the skyline to the south-east, offering a frame but not the dramatic elevated setting that many comparable tombs command.

On the summit of the mound, set a few metres in from its edge, a circle of large boulders some 16 metres in diameter sits in varying states of preservation. The south-western arc remains the most coherent, with close-set stones standing between 0.8 and 1.1 metres high; elsewhere the circuit is broken by gaps, most noticeably to the north and south-east. Near the centre of the circle, larger stones protrude from a slight hollow, likely the remains of the burial chamber. A pair of smaller matched stones, each about 0.7 metres long and set roughly 0.8 metres apart, stands just to the east of the chamber; these are thought to be what survives of the passage itself, oriented east to west. The tomb was recorded by the archaeologist Michael Herity in 1974, who described a ring of boulders 21 metres in diameter with a boulder-built chamber at its centre. A later inspection in 1995 found the overall layout broadly consistent with his account, though a dense growth of gorse and brambles made a thorough examination difficult and left some details uncertain. Notably, the site does not appear on the Ordnance Survey six-inch mapping of 1837 to 1838, though it is marked on the 1922 edition, suggesting it either escaped the earlier surveyors' notice or was not sufficiently visible at that time.
