The National Monuments Service's description
On a slight promontory with a deep ravine to the N and overlooking Caherglassaun Lough from E to S. In existence in 1574 when it was the possession of ‘Oheyn’ (Nolan 1901, 114). This rectangular tower house (9.35m E-W, 8.1m N-S ) survives to a height of three/four storeys. It is constructed of large well-coursed limestone blocks and mortar, and dressed quoinstones; the latter have been robbed out of the SE corner. A base-batter rises to the 1st-floor level. The original doorway, much destroyed, is in the E wall. It accesses a small lobby with an overhead murder-hole. Further doorways off it lead to the stairs to the N and the main ground-floor room to the W. The stairs runs straight initially but spirals anticlockwise from the NE corner to the top of the tower. Only a few of its steps survive. It is lit by flat-headed loops and angle loop at 1st-floor level. The floor of the main room is littered with rubble due to the collapse of the internal wall-faces of the W and N walls. It was lit by three narrow slit windows set in deep embrasures. Only that in the S wall survives intact. Those in the W and N walls are destroyed; a large breach marks the location of that in the N wall. Due to collapse of the wall-face, the garderobe exit chute is visible both internally and externally at the W end of the N wall. Corbels in the N and S walls indicate that the floor above was wooden. There is a stone vault between the 1st/2nd floor. A fireplace in the S wall in the main room on the 1st floor is a later insertion as it blocks an earlier single-light ogee-headed, which is visible in the external wall-face. The windows in the W and N walls at this level comprise square two lights (both missing their central mullion) and a rectangular flat-headed light in the E wall that was inserted into an earlier slit window. An intramural garderobe passage, in the haunches of the vault, is accessed off the stairwell and runs E-W along the N wall. It is lit by two flat-headed loops. Another opening off the stairs above this accesses a narrow chamber running N-S along the E wall. It is lit by a flat-headed loop in the S wall. The 2nd floor comprised one room but it is not accessible. The original parapets are gone, apparently felled by an earthquake in 1755 (Mac Eoin 1981). (Nolan 1901, 114; Fahey 1893, 113).
