Whilst the main tower house commands attention, it's the surviving sections of the bawn wall that offer a glimpse into how these castles once functioned as defensive compounds. The wall, which originally enclosed the tower house in a protective perimeter, still stands along the northern and western sides of the site.

The most distinctive feature of these remaining walls is a circular flanking tower tucked into the northwest corner. With an internal diameter of 3.6 metres, this rounded structure would have served as a crucial defensive position, allowing defenders to cover the approaches to the castle from multiple angles. These flanking towers were essential elements of bawn design, eliminating blind spots that attackers might otherwise exploit.

The castle's archaeological significance has been well documented, with detailed surveys mapping out the surviving structures. These remnants represent a common pattern in Irish tower house construction, where the main residence was typically surrounded by a bawn; a fortified courtyard that provided space for livestock, storage buildings, and offered protection to the castle's inhabitants and their retainers during times of conflict.
