The site sits at the end of a northwest to southeast ridge, naturally protected by the Annestown stream valley to the east and a steep ravine carved by a tributary to the west. This strategic location would have made it an ideal spot for a fortified structure, with sheer cliffs dropping some 30 metres on the north and east sides, providing natural defences that any medieval builder would have envied.

What survives today are fragments of the south wall, standing roughly 3 metres high, along with foundations of the western wall. The structure appears to have been relatively modest in size, measuring approximately 10 metres square, and likely served as either a bawn; a fortified courtyard typical of Irish tower houses; or possibly a hall. The defensive nature of the site is evident from the remains of an embrasure in the south wall, which would have allowed defenders to fire upon attackers whilst remaining protected behind the stonework.

The bawn connects directly to Dunhill tower house, with evidence of a round-arched gateway still visible where it springs from the tower house’s south wall. A rebate for the doorway can still be traced in the stonework, showing how the two structures were integrated into a single defensive complex. This combination of tower house and bawn was common throughout medieval Ireland, providing both a secure residence and a protected area for livestock and supplies during times of conflict.
