The MacSweens had to surrender Skipness when the Norwegian force under Hakon was defeated at the Battle of Largs in 1263. Castle Skipness then passed to the MacDonalds, who were probably responsible for adding the strong curtain wall with its distinctive crosslet-arrowslits and crenellations. They also added a new chapel a short distance away, linked by a looping trail to the current castle. The new Kilbrannan Chapel enclosed an earlier, redundant chapel dedicated to St Columba. Within the chapel is a small collection of finely carved grave slabs.
In 1493 the MacDonalds lost Skipness to the Campbells, earls of Argyll. It was under the Campbells that an impressive tower house was built in the north east corner of the castle enclosure. But by 1700 Skipness was abandoned, and it has mouldered away for the past three centuries.
The castle is well worth exploring, but please do take the time to stroll to the chapel by the shore. The carved stones (some protected beneath a solid cover) are well worth visiting. The location, looking across the Arran, is simply marvellous.
