The flat-topped summit, roughly circular in shape, measures about 18 metres from north to south and 16 metres from east to west. While the Ordnance Survey’s second edition 6-inch map from the late 19th century appears to show a single-ringed enclosure at this location, it’s possible the cartographers were simply depicting the distinctive profile of the hill itself.

Today, only subtle traces hint at what might once have stood here. A short section of earthen bank, rising about half a metre high, can still be seen on the southeastern side of the hilltop. On the northwest, another stretch of bank runs for about 10 metres, though it stands only 30 centimetres high. If these fragments do represent the remains of an enclosure, as archaeologists suspect, the structure would have had an internal diameter of approximately 12 metres; a modest but defensible space that would have commanded views across the surrounding landscape.

The hill itself is covered in rough pasture grass, while the lower ground around it tends to be boggy and waterlogged, creating a natural barrier that would have added to the site’s defensive qualities. This archaeological survey information comes from the comprehensive 1983 survey of County Donegal’s field antiquities, which catalogued sites ranging from the Mesolithic period through to the 17th century, with updates added as recently as 2011.
