This rectangular tower house, built from roughly coursed limestone rubble, once commanded views across the low-lying pasture from its strategic position facing south-southeast to northwest. Though centuries of neglect have taken their toll, sections of the northwest and northeast walls still rise three storeys high, offering glimpses of what was once a formidable defensive structure measuring approximately 9.5 metres by 7.4 metres, with walls nearly two metres thick.

The castle’s documented history stretches back to at least 1621, when Connell McMurogh O’Feroll received a land grant that included ‘the castle and lands of Bealalcare and a water-mill’, suggesting this was already an established settlement with economic importance. The structure even merited inclusion on an early 17th-century map of Moydow barony, now preserved in the British Library’s Cotton manuscript collection, indicating its significance in the local landscape during that period.

Today, visitors can still make out traces of the castle’s original layout despite extensive collapse. The lower section of a doorway jamb remains visible near the southern end of the northwest wall, with a large rectangular alcove positioned just inside to the north; likely once used for storage or perhaps as a guard post. At first floor level in the northeast wall, a simple rectangular opening marks where a window once provided light to the upper chambers. These surviving architectural details, though sparse, help paint a picture of daily life in a structure that served both as a family residence and a defensive stronghold during Ireland’s tumultuous medieval and early modern periods.
