A field of pasture runs to within a hundred metres of Lough Conn's north-eastern shore, and nothing in the grass gives any indication that something once stood here. Yet viewed from the air, the soil tells a different story: a subcircular cropmark, roughly 31 metres east to west and 26 metres north to south, traces the outline of an enclosure that has otherwise been entirely erased from the landscape.

The site appears on the Ordnance Survey six-inch map of 1838 as a circular, rath-like enclosure. A rath, sometimes called a ringfort, is a roughly circular earthwork, typically defined by one or more banks and ditches, that served as a farmstead or defended homestead during the early medieval period in Ireland. By the time the map was revised in 1930, the feature was still recorded, shown with hachuring and set within a wooded, fenced-off area, suggesting it had some degree of protection at that point. At some stage after that, it was levelled completely. The vegetation above its buried outline still responds to what lies beneath, and in dry summers, when grass over disturbed or compressed soil dries out at a different rate to the surrounding pasture, the ghost of the enclosure re-emerges as a cropmark visible only from above.
