What is recorded here

Carriganass Castle is a ruined tower-house and rectangular bawn on the north bank of the Owvane river in County Cork, probably built in the 17th century. Tradition credits Dermot O'Sullivan with building it about 1540 for the O'Sullivan clan, and it surrendered after Dunboy fell in 1602. Its west wall still rises four storeys with gun loops, corner towers, and faint vault shadows inside, while the east half was changed into disused farm buildings.

On N bank of Owvane river commanding view in all directions; overlooked from N. Remains of tower-house stand in SW quadrant of rectangular bawn. W wall of tower (Wth 10.3m), most of N wall (L 12m) and short return of S wall (L 2m) stand to four storey. 'Ghost' of segmental vaults over 1st and 3rd floors visible on inside of W face (axis E-W). Central window opes in W wall at all levels; first floor embrasure has mural passage on either side; single ogee-headed light at 3rd floor. Small mural chamber in N wall at 1st floor level; mural passage visible in broken face of S wall at 3rd floor level. Similar bartizans atop NW and SW corners: supported by a corbel on each wall with a straight face set across corner. Bawn roughly rectangular in plan (26m N-S; 48m E-W) projecting towers at each corner; S face overlooks rock-cut gorge. Appears late in date, probably 17th century. Eastern half altered to accomodate modern farm buildings (now disused). W wall and original W end of N wall pierced by many gun loops. Outward facing corners NE and SE corner towers acutely angled, similar to bastions on star-shaped forts; NW tower more bluntly pointed; SW tower roughly rectangular. SW tower has 4 tiers of nesting boxes on each face at 1st floor level. Castle of the O'Sullivan clan reputedly built by Dermot O'Sullivan about 1540 (Healy 1988, 170); surrendered after the fall of Dunboy in 1602 (O'Murchadha 1985, 308).

Carriganass Castle was built by the McCarthy family, Lords of Bantry, in the late 15th or early 16th century. It is remembered as a significant stronghold of the McCarthy dynasty and as one of the few surviving tower-houses in the area, reflecting the defensive architecture of west Cork during the Gaelic period.
