The present Carrick Castle is possibly the third on 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. In the spring of 1307, Robert the Bruce drove Henry Percy from the Castle before conducting a guerrilla war against Edward I of England. Edward had given the castle, which belonged to Robert, to Percy. In 1368 it then passed on to the Campbell Earls of Argyll. The third structure, the late 15th-century castle, was a royal stronghold, held by the Earls of Argyll as hereditary keepers, and was the symbol and source of their power in South Argyll. It was one of their three chief castles, the other two being Duart and Fincharn.
In 1685, during the rebellion of Archibald Campbell, 9th Earl of Argyll, against King James VII, HMS Kingfisher bombarded the castle, badly damaging the keep, which lost its roof. The castle was intermittently occupied until it was sold to the Murrays, the Earls of Dunmore. The keep was a ruin for many years but is now in private ownership and undergoing restoration.
Carrick 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.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
