Richard Browne and his wife Mary Plunket built this fortified house shortly after 1620, following their grant of lands from King James I. Originally, the castle consisted of three blocks arranged in an L-shaped plan, all enclosed within a protective bawn that was divided into two sections by a cross-wall extending from the north wall of the house.

Today, only fragments of this once-imposing structure remain standing, primarily an L-shaped section of rubble limestone walling now draped in ivy. The best-preserved portion is the eastern wall of the main block, which rises three storeys high and stretches 18.5 metres in length. Six gun loops pierce the ground floor, strategically positioned to defend the southeastern quadrant of the bawn, whilst the first floor retains traces of two large windows, now broken out. The northern wall of the smaller block, standing just one storey high, features two additional gun loops that would have provided flanking fire along the eastern face of the house. Wooden beam holes visible in the walls indicate that all the floors were timber constructions.

The castle’s defensive features speak to the uncertain times in which it was built, when English and Scottish settlers like the Brownes required fortified dwellings in their new Irish lands. A natural spring well, now partially covered with boulders, sits just outside the western bawn wall; a practical water source that would have been essential during any siege. About 440 metres southeast of the castle ruins, a church and graveyard contain a memorial stone to Richard Brown and Mary, connecting these scattered fragments of stone to the very real people who once called this place home.
