This stone fort, with average wall heights standing about 2.75 meters and over three metres thick, dates back to the early Christian period. Within the site is a souterrain about fifteen metres long and over two metres high and remains of dwellings. It is situated 2 miles (3 km) south west of Castlewellan (Irish Caisleán Uidhilín) off the A25 road to Rathfriland, County Down, north of Ireland (Irish: Ráth Fraoileann, Contae an Dúin, Tuaisceart Éireann). It is close to the small man-made lough Lough Island Reavy.
