Originally marked on the first edition Ordnance Survey 6-inch map as ‘Togher Castle’ and later renamed ‘Togher Monastery’, these limestone rubble walls tell a complex story of medieval defensive architecture. The rectangular structure, measuring 13.1 metres north to south and 11.5 metres east to west, rises two storeys with remnants of a base batter still visible at ground level.

The tower house’s ground floor demonstrates sophisticated medieval planning with its division into two barrel-vaulted chambers running north to south. The original entrance on the south wall, though now destroyed, once led to a guard room in the southeast corner; only a musket loop remains as evidence of this defensive space. From this entrance, spiral stairs in the southwest corner and a mural staircase in the east wall both provided access to the first floor, an unusual dual-stair arrangement that sets this tower apart from typical examples. The ground floor chambers feature large wall niches and projecting corbels, with the western room being the more spacious of the two.

The first floor, though partially collapsed with only the eastern half surviving, reveals even more intriguing features. A mural passage runs along the eastern wall, accessed by descending four steps through what was once a doorway. This passage contains two small slit openings with rounded heads and a slop stone beneath one of them, eventually leading to a garderobe with its outlet on the north wall’s eastern end. Remarkably, an adjoining western room contained a second passage with another garderobe outlet, giving the tower house two separate privy facilities on the same floor; a level of domestic sophistication not commonly found in such structures. These architectural details, combined with the tower’s defensive features, paint a picture of a carefully planned late medieval residence that balanced both comfort and security.
