The site sits in a natural amphitheatre of sorts, with a sharp, gorse-covered ridge rising just 30 metres to the west, whilst the ground drops away abruptly to the east. The weathered lower walls of an old masonry building stand immediately northeast of the ancient stones, a much later addition to this prehistoric site.

What remains today is a puzzle that has confounded archaeologists for generations. Two large stone slabs stand opposite each other, aligned north-northeast to south-southwest and separated by less than a metre. The eastern stone, standing 1.8 metres tall, leans away from its western companion, which reaches only a metre in height, though it may once have been taller. Various other stones lie scattered about; some appear to have been deliberately broken, whilst others may belong to old field boundaries rather than the monument itself. The two tall uprights look remarkably like the portal stones that would have flanked the entrance to a megalithic chamber, but without more evidence, the monument's original purpose remains tantalisingly unclear.

Local tradition has long associated the site with ancient lore; when antiquarian Thomas Fagan visited in 1846, he recorded that locals called it 'Grania's Bed', referencing the legendary Gráinne of Irish mythology and suggesting it was a 'druidical sepulture'. Fagan counted eight stones at the site during his visit, considerably more than survive today, though his account doesn't make their arrangement clear. Whether this was once a portal tomb, a court tomb, or something else entirely, the monument at Convoy Demesne continues to guard its secrets, offering visitors a chance to contemplate the engineering ambitions and spiritual beliefs of Ireland's Neolithic inhabitants.
