What remains today are the substantial walls of a bawn, or fortified enclosure, that once protected a castle or tower house at its southeastern corner. The Civil Survey of 1654-6 recorded these as ‘the walls of an old Bawne’, noting that the property belonged to Thomas Magher of Bollybane, described as an ‘Irish Papist’. Though the castle itself has vanished, its foundations were reportedly still traceable when the Ordnance Survey visited in the 19th century.

The bawn’s defensive walls, built from roughly coursed sandstone rubble bound with sandy clay and pebble mortar, still stand impressively along the north and east sides. The northern wall stretches 33 metres whilst the eastern wall rises to about 8 metres high, both featuring a slight base batter and evidence of former parapets. A 4.6 metre wide breach in the north wall likely marks the original entrance, with an arched niche visible in the interior face and remnants of an angled wall projecting outward. The western wall, though overgrown, remains visible, whilst the southern wall has been completely levelled over time.

The site bears evidence of both habitation and exploitation; a steep drop immediately north of the bawn resulted from quarrying for building stone, which coincidentally provided additional defence. The 1943 Irish Tourist Association survey noted foundations of several outbuildings to the south, though these have since disappeared. Today, low mounds scattered throughout the interior offer no clear pattern of the structures that once stood here, leaving visitors to imagine the fortified homestead that dominated this pastoral landscape for centuries.
