The enclosure measures roughly 32 metres east to west and just over 31 metres north to south, its outline marked not by any surviving wall or bank but by a scarp, a slope in the ground where the edge of the monument has eroded away over centuries. A modern field boundary cuts across it from the north to the north-east, compounding the wear. At the centre, a small earthen mound just under three metres across sits quietly within the circuit. It is this mound, rather than the enclosure itself, that carries the most intriguing local attribution.

Local tradition and earlier antiquarian sources hold that the interior mound is the burial place of a figure known as King Turlough. The name appears in Killanin and Duignan's 1967 guide to Irish buildings and monuments, and references to the site also appear in earlier works by Neary and Knox from the first decades of the twentieth century. Whether the Turlough in question was a local lord, a forgotten king of one of the many competing Connacht dynasties, or a figure whose memory has shifted through oral tradition over the generations, the notes do not say. The name Turlough itself, from the Irish Toirdhealbhach, was common among medieval Connacht nobility, which gives the tradition a plausible enough context without confirming anything specific. Adding to the sense of layered history, Dunmore Castle lies approximately 250 metres to the east, close enough to suggest that whoever occupied or used this enclosure did so within a landscape already shaped by other seats of power.
