The site consists of a four-storey tower house with an attic and a remarkably well-preserved bawn, or defensive courtyard, that stretches approximately 45 metres north to south and 54 metres east to west. Built from roughly coursed limestone rubble with substantial, well-cut corner stones, the tower house features a distinctive two-storey turret along its northern wall and a tall, slender base batter reaching 2.4 metres in height.

The bawn represents two distinct construction phases; the first dates to the late fifteenth or early sixteenth century when the tower house was built, whilst the second phase saw significant modifications during the seventeenth century, including the addition of circular towers at the northeast and southwest corners and a bartizan at the northwest angle. The defensive walls once supported a wall-walk that gave access to cross-loops for firearms, with two surviving in the north wall and one each in the east and west walls. The southwest angle tower, measuring 2.5 metres internally with walls 1.5 metres thick, rises three storeys and features gun loops of various shapes; square, round, and cruciform; at every level, all accessed via mural stairs with wooden floors throughout.

Historical records from the Civil Survey of 1654-6 describe the site as ‘a bawne and castle in repaire’, with William Cantwell listed as the proprietor in 1640. The northeast tower underwent significant alterations in the late eighteenth or nineteenth century when it was converted into a summerhouse or gazebo, complete with plastered interior walls and modified windows. Among its more refined features is a beautifully executed first-floor fireplace with roll-moulding on the jambs, displaying both punch and diagonal tooling techniques. Intriguingly, a sheela-na-gig, a type of medieval stone carving, was once located in the tower house’s south wall, though it has since been lost.
