The castle sits strategically between bogland to the west and dry land on its other three sides, with a stream running between the structure and the bog. Despite its local moniker, nothing definitive is known about the castle’s history; it doesn’t even merit a mention in the Civil Survey of 1654 to 1656, leaving its origins and purpose shrouded in mystery.

What remains of the structure suggests it may have been a 17th-century plantation building rather than a traditional medieval castle. The surviving portions consist mainly of a section of the west wall, stretching 8.6 metres in length and standing about 2.5 metres high, along with parts of the north wall that extend 13.5 metres from the western corner. The construction shows roughly coursed limestone rubble with traces of both internal and external render still visible on the walls. A slight base batter on the north wall and the remains of a destroyed window in the west wall are the only architectural features that have survived the centuries.

Aerial photographs from 1966 reveal that the castle once stood at the centre of an oval-shaped enclosure, complete with linear earthworks and what appears to be a sunken road approaching from the east. These features, now barely visible at ground level, hint at a more substantial complex that once occupied this windswept hilltop. The building’s construction, using local limestone without any cut stones, and its relatively modest dimensions suggest this was likely a functional structure built during the plantation period rather than a grand defensive fortress of earlier centuries.
