Now incorporated into the northwest corner of a garden wall surrounding Cloyne House, this rectangular structure once measured approximately 20.7 metres north to south and 18.15 metres east to west. Though time has taken its toll, with the northern wall reduced to a single storey and only fragments of the southern and eastern walls surviving, the western wall still impressively rises to two storeys, its upper reaches covered in ivy.

The building’s defensive character becomes clear upon examining its western face, where four rectangular window openings reveal the structure’s military past. These lights, measuring 85 centimetres high and 35 centimetres wide with chamfered outer edges, are arranged with two at ground level and two slightly offset on the first floor; all have their interior embrasures blocked. Near the northwest corner at ground level, two small oval openings arranged vertically once formed a gun loop, though this embrasure too has been filled in. The interior space is now little more than an open area scattered with rubble from the collapsed portions of the building.

Historical records add an intriguing layer of mystery to these ruins. Writing in 1903, Fleming noted that Cloyne once boasted at least three castles, though frustratingly, none can be definitively linked to this particular structure. Whether this fortified house served as a merchant’s defended residence, a minor noble’s stronghold, or fulfilled some other defensive purpose in Cloyne’s turbulent past remains uncertain, leaving visitors to imagine the stories these stones could tell.
