Carrick Castle is a 15th-century tower house on the west shore of Loch Goil, Argyll, Scotland. It is located between Cuilmuich and Carrick, 4 miles (6.4 km) south of Lochgoilhead. The Castle consists of two floors above the central great hall. The building is oblong, 66 feet long by 38 feet wide, with walls seven feet thick. It stands 64 feet high. There is a curiosity – a small chimney is built into a window recess. There is an appendage of a smaller 17th Century structure to the original rectangular tower house.
The present ruin is possibly the third occupant of this location. The first may have been a Viking fort. The second structure, and first castle, is believed to have been built in the 12th century. Allegedly a hunting seat of the Scots kings, Carrick was originally a Lamont stronghold.
