The castle and bawn, dating from different periods, sit atop a raised earthwork that’s still visible today as a scarp about 0.62 metres high, with a berm extending 7.5 to 11.55 metres beyond the structures. The site comprises a fortified house and a smaller dwelling at the western corner, both incorporated into what was once a rectangular bawn measuring approximately 40 metres northeast to southwest and 46 metres northwest to southeast.

The defensive bawn walls have largely vanished, though early 20th century Ordnance Survey maps from 1903-04 show that the northern and eastern edges were once defined by earthen banks. Today, only a single stretch of bawn wall survives, connecting the southwest gable of the fortified house to the smaller house about 14.5 metres away. This surviving section appears to date from the 17th century rebuilding rather than the original castle construction, with most of it reduced to just the lower courses. Tie stones projecting from the smaller house’s southeastern wall indicate where the bawn once continued, reaching up to first-floor level.

The fortified house itself shows evidence of multiple building phases. While the bawn wall seems to have been integrated into the western end of the house’s northwest wall during the 17th century modifications, a separate wall projecting from the eastern end of the northeast wall represents later 18th century alterations. These layers of construction and reconstruction tell the story of a site that evolved over centuries, adapting to changing defensive needs and domestic requirements whilst maintaining its strategic position on this river island.
