Carrignamuck Tower House, Medieval tower house ruins in Carrignamuck, County Cork, Ireland.

Carrignamuck Tower House is a five-story L-shaped ruin in County Cork featuring battlements and narrow slit windows. The structure displays typical features of 15th-century Irish defensive architecture with thick stone walls and limited openings.

The tower was built by Cormac Laidir MacCarthy, Lord of Muskerry, and faced bombardment in 1650 during the Cromwellian campaign. Attackers fired from nearby Meeshal Hill, demonstrating its strategic importance during that period.

Local tradition calls the tower Carrig Cormac after Cormac Laidir MacCarthy, and one account links the name Carrignamuck to a nearby spot where pigs were slaughtered to supply bacon. The tower was the official residence of the Tanist, heir to Blarney Castle, and in 1944 it belonged to John O'Shaughnessy of Dripsey Woollen Mills.

The tower sits about 3 kilometers north of Coachford village and remains private property, so visits require permission from the owners beforehand. You can view it from nearby, but always check locally before traveling to ensure access on the day.

The timber window frame said to come from the former Church of Ireland parish church at Aghabullogue sits on the first floor, not the ground floor, in one of the chambers beside the garderobe and murder-hole. It was inserted during the 1866 repairs, when a slate roof, fireplaces and a wooden front door were also added.
