It measures roughly 11.6 metres across, defined on its north-eastern edge by a scarp rising to about two metres, with traces of an external fosse and outer bank visible from the south around to the west. A fosse is simply a ditch, typically dug to throw up the bank beside it, and the combination of platform, scarp, and fosse gives the feature a deliberate, constructed quality. What that construction was actually for, however, remains genuinely open.

The nineteenth-century Ordnance Survey six-inch maps recorded something larger here, a circular enclosure closer to twenty metres in diameter, suggesting that what survives today is a reduced version of the original. A reference by Neary in 1914 noted the site, but offered no firm interpretation. The range of possibilities put forward since then covers considerable ground: a house platform, some kind of designed landscape feature, or a windmill mound. Windmill mounds, raised bases constructed to elevate a mill and catch the wind above surrounding obstacles, were used in Ireland from the medieval period onward, though they are not especially common and rarely survive in identifiable form. Adding a further layer of interest, a broadly similar monument sits just seventy metres to the west-south-west, which raises the question of whether the two were ever related in function or simply share a landscape by coincidence.
