Known locally as St Elba's Grave, the site is not a grave in any archaeologically verified sense, but rather an accumulation of objects and belief that has gathered around this large flat stone over an unknowable span of time. Beside it stands a modern granite cross, nearly three metres tall on a tiered plinth, and on the lowest tier of that plinth visitors have left tokens, including euro coins tucked into a tin, a quietly matter-of-fact sign that the place is still in active use.

The flat slab itself is uninscribed and gives little away. At its north-east end, an upright limestone slab, shaped but not finely dressed, carries the letters IHS, a Christogram derived from the Greek rendering of the name of Jesus, though here the S has been reversed, suggesting the work of a carver working by eye rather than from a formal model. A roughly square limestone flag is cemented on top of this upright piece, and the whole assembly sits adjacent to the modern cross, which bears the inscription AMDC across its arms. The tradition attached to the large flat stone holds that it is the grave of Saint Aillbe, a figure whose name is also preserved in the nearby holy well, Toberelba, just eight metres to the south-west. According to local belief, a person suffering from illness who manages to sleep soundly on the stone overnight will be cured of their ailments. A penitential station, a site used for the formal circuits of prayer associated with Irish pilgrimage practice, lies only a short distance to the south-east, suggesting this is one node within a small but coherent devotional landscape rather than an isolated curiosity.

The site sits in open bog, which means the approach is likely to be wet underfoot regardless of season, and the slab's edges remain obscured by encroaching peat. The coins in the tin, and the cross erected above a modest but carefully assembled plinth, are probably the most telling details on the ground: a saint whose historical existence is uncertain, a stone that may pre-date Christianity entirely, and pilgrims still coming to leave something behind.
