On the wide, flat expanse of the Curragh in County Kildare, a Bronze Age burial monument sits quietly between an eighteenth-century execution site and a functioning military camp, unnoticed by most who pass nearby. The monument is a ring barrow, a form of funerary earthwork typically consisting of a raised central mound surrounded by a circular ditch, or fosse, and an outer earthen bank. This one is a reasonably substantial example: the central area measures roughly 25 metres across and rises about 2 metres above the surrounding plain, while the full diameter of the monument, taking in the fosse and outer bank, reaches approximately 38 metres.

The site was recorded by the archaeologist Seán P. Ó Ríordáin in 1950, where it appears as Site X, accompanied by a scaled east-west cross-section. That published record remains one of the main sources of measured detail for the monument. Gaps and causeways at the north-north-east and south of the earthwork are considered likely to be modern intrusions rather than original features, and the interior shows some degree of disturbance. Clumps of whins, the low thorny shrub known elsewhere as gorse or furze, are beginning to colonise the mound, a sign of gradual encroachment that is common on unmanaged earthworks across the Irish midlands. A second ring barrow of similar type lies roughly 160 metres to the north-east, and the site known as Gibbet Rath, a place with its own grim history, sits to the west, making this a corner of the Curragh that layers the prehistoric and the historically violent in unusually close proximity.
