Tarbert Castle was a strategic royal stronghold during the Middle Ages and one of three castles at Tarbert. The castle overlooks the harbour and although pre-14th century in construction, the tower dates back to 1494 and the visit of James IV to the Western Highlands.
In 712, Tarbert was burned by King Selbach mac Ferchair of Cenél Loairn and of Dál Riata and in 731 by his son, Dúngal mac Selbaig.
King Edward II of England handed control of the castle to the Scottish King John II de Balliol in 1292. A fortified structure was built in Tarbert during the 13th century. It was reinforced with the addition of an outer bailey and towers in the 1320s by Robert the Bruce, to protect it against the Lords of the Isles. A towerhouse was added in the 16th century, which is the most noticeable part of the remains. The castle occupies high land above the village, providing views up Loch Fyne and beyond to the Firth of Clyde. This castle was captured from John MacDonald of Islay, Lord of the Isles by James IV of Scotland as part of his campaign to destroy the power of the Lords of the Isles in 1494. In 1687 the castle was involved in another skirmish when Walter Campbell of Skipness Castle seized it as a stronghold for Archibald Campbell, 9th Earl of Argyll as part of actions in support of the Monmouth Rebellion in England.
There are only a couple of standing walls left and they are considered unstable. The castle has a very commanding view of the water approaches.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
