The tower house sits at the western end of a rectangular bawn measuring 32 metres north to south and 52.6 metres east to west, with a small lake visible about 150 metres to the south. The Civil Survey of 1654-6 records that the Countess of Ormond owned the property in 1640, though by then it was already described as ‘a castle Demolished with a Bawne on one side thereof’, alongside a thatched house and several small cabins that were still inhabited.

The bawn’s construction reveals two distinct phases of building. Originally built in the 15th century, the western wall ran directly up to the tower house, though it wasn’t structurally bonded to it. In the late 16th century, significant modifications were made: the northern end of the western wall was extended to enclose rather than simply meet the tower house, creating a defensive projection that juts out nearly five metres beyond the original wall line. This extension features two circular, two-storey towers at its northwest and southwest corners, both topped with distinctive corbelled roofs. The main entrance to the bawn, a round-headed archway measuring two metres wide and 2.8 metres high, sits in the northern wall near the northwest angle, flanked by external buttresses and defended by narrow loops above and beside the doorway.

The southern wall contains a 15th or 16th century postern gate, flat-headed and externally chamfered, with a hanging-eye on its eastern side; the first edition Ordnance Survey map shows an earthwork funnelling out from this secondary entrance to form a roughly square platform, though this feature is no longer visible above ground. Internal buildings were incorporated into both the southwest and northeast angles of the bawn, with the southwestern structure showing three openings in the southern wall that may have been modified into windows, plus one large opening in the western wall. The bawn walls, measuring 1.45 metres thick, demonstrate the substantial nature of these medieval defences, whilst the gun-loops in the angle towers’ embrasures show how the fortification was adapted for firearms during its later phase of construction.
