A ringfort is a roughly circular enclosure, typically of early medieval date, defined by an earthen bank and outer ditch, and used as a farmstead or defended homestead. What makes this particular example quietly remarkable is not just the enclosure itself but the unusually well-preserved house structures still legible inside it, their walls and room divisions readable in the grass after more than a thousand years.

At the centre of the ringfort sits the main house, a raised rectangular platform measuring 12 metres north to south and 22 metres east to west, divided into two rooms aligned on an east-west axis. The larger western room measures roughly 8 metres by 3.5 metres internally, while a smaller annexe-type room to the east runs about 5 metres by 2.5 metres. Both are enclosed by an earth and stone bank, still standing around 0.6 metres above the surrounding ground on its outer face, with an outer fosse, or ditch, some 3 metres wide at the top. A gap roughly 1.8 metres wide in the northern part of the bank may mark an original entrance. A second house sits just 3 metres to the north of this central structure, in the northern quadrant of the enclosure. Both buildings appear to be contemporary with the ringfort itself, and both are described as being in very good condition. A castle site lies about 270 metres to the north, and a church and graveyard around 195 metres to the southwest, suggesting this was once a fairly busy corner of the early medieval landscape. A 1640 Civil Survey description of the nearby lands of Kilcornan mentions an "old castle irrepairable and some cabbins wast," which may or may not refer to these structures. The house footings do not resemble castle remains, and they are more plausibly the domestic buildings of the ringfort's original inhabitants, the 1640 reference perhaps reflecting confusion, or a now-vanished castle elsewhere in the townland.
