This square enclosure, measuring just under 51 metres on each side, represents a classic example of Anglo-Norman defensive architecture in Ireland. The site retains traces of its impressive defensive features, including a deep, wide fosse (defensive ditch) and an earthen mound that protected the southern, western, and northern sides of the enclosure.

The most striking feature of this fortification was the tower house that once stood at the southeast corner, though today only its stump remains visible. Tower houses were the preferred fortified residences of the Irish gentry from the 15th to 17th centuries, combining defensive capabilities with domestic accommodation. These vertical stone castles typically featured thick walls, narrow windows, and multiple floors accessed by spiral staircases; all designed to withstand siege while providing comfortable living quarters for their noble inhabitants.

First documented in detail during O’Flanagan’s survey work in 1928, the site offers valuable insights into medieval settlement patterns and defensive strategies in the region. The combination of earthwork defences with a stone tower house suggests this was an important local stronghold, likely controlling routes through this part of Wicklow. While time and weather have reduced much of the structure to ruins, the remaining earthworks and tower foundations continue to mark this spot as a significant piece of Ireland’s medieval heritage.
