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:Ogrodzieniec Castle is a ruined medieval castle originally built in the 14th–15th century by the W³odkowie Sulimczycy family. Established in the early 12th century, during the reign of Boles³aw III Wrymouth, the first stronghold was razed by the Tatars in 1241. In the mid-14th century a new gothic castle was built here to accommodate the Sulimczycy family. Surrounded by three high rocks, the castle was well integrated into the area. The defensive walls were built to close the circuit formed by the rocks, and a narrow opening between two of the rocks served as an entrance.
In 1470 the castle and lands were bought by the wealthy Cracovian townsmen, Ibram and Piotr Salomon. Then, Ogrodzieniec became the property of Jan Feliks Rzeszowski, the rector of Przemy¶l and the canon of Cracow. The owners of the castle about that time were also Jan and Andrzej Rzeszowskis, and later Pilecki and Che³miñski families. In 1523 the castle was bought by Jan Boner.
