The 1842 Ordnance Survey map reveals the site’s former glory, showing four towers positioned at the corners of a large square enclosure, roughly 50 metres apart, with a house at its centre. Today, only the northwestern tower survives intact, whilst the southwestern tower has been reduced to overgrown mounds of rubble, and the other two have vanished entirely without leaving any surface traces.

The surviving tower is circular in plan with an internal diameter of 3.5 metres, featuring a door that opens to the north and southeast; the latter opening appears to be in its original position, though both have been fitted with recent surrounds. Six evenly spaced gun loops pierce the walls, their lintelled openings providing defensive firing positions around the structure’s circumference. The first floor has been largely rebuilt and lacks any distinctive features, whilst walls extending from the tower along the line of the original bawn enclosure appear to be later additions, as they aren’t keyed into the tower’s masonry.

Based on its architectural features, the tower likely dates to the early 17th century and would have protected a fortified house that was subsequently replaced by the current Ballinterry House in the late 17th century. Curiously, this defensive structure wasn’t recorded by Healy in 1988, and its early history remains something of a mystery, with no known documentation about its origins or the families who built and occupied it.
