It looks, from a distance, like a slight thickening of the ground, grass-covered and easy to dismiss as a natural feature. But the geometry tells a different story: an enclosure roughly 50 metres north to south and 42 metres east to west, with a bank up to seven and a half metres wide, enclosing a deliberately dished interior. A modern field fence cuts across its eastern edge, and the eastern portion of the structure has largely disappeared into the neighbouring field, leaving the western half as the clearest evidence of what once stood here.

At the centre of the enclosure sits something stranger still: a stone and earth mound, sometimes called a cairn, measuring roughly 14 metres across and nearly half a metre high, with a circular depression five metres in diameter cut into its top. The bottom of that hollow sits about 39 centimetres below the crest of the mound, giving it the quality of a shallow bowl set within a low platform. A second, less well-preserved mound abuts the first on its northern side. No external ditch was identified during survey, and no obvious entrance has survived. Enclosures of this kind in Ireland are often associated with early medieval settlement, ritual activity, or burial, though without excavation it is rarely possible to say which function, or combination of functions, a particular site once served. The central mound with its depression is the detail that most resists easy explanation; it is not typical of a simple ringfort, the most common type of enclosed settlement from the early medieval period, and may point to something older or more ceremonially significant. The survey of this area was carried out in 1996 and 1997.
