Castle Tioram ruins sits on the tidal island Eilean Tioram in Loch Moidart, Lochaber. The castle is the traditional seat of Clan MacDonald of Clan Ranald, a branch of Clan Donald. It was seized by Government forces around 1692 when Clan Chief Allan of Clanranald joined the Jacobite Court in France, despite having sworn allegiance to the British Crown. A small garrison was stationed in the castle until the Jacobite Uprising of 1715 when Allan recaptured and torched it, purportedly to keep it out of the hands of Hanoverian forces. It has been unoccupied since that time, although there are some accounts suggesting it was partially inhabited thereafter including storage of firearms from the De Tuillay in the 1745 Jacobite Uprising and Lady Grange's account of her kidnapping.
The curtain wall is believed to date from the 13th century whilst the tower and other interior buildings are of 15th to 17th century construction. Amie mac Ruari is said to have extended the castle in the 14th century.
The castle is now in extremely poor condition and in 1998 was closed to the public at the request of Highland Council; a major structural collapse occurred at the north west curtain wall in 2000.
The castle can be reached on foot across the tidal causeway, but there is no access to the interior because of the risk of falling masonry.
References:Château de Niort is a medieval castle in the French town of Niort. It consists of two square towers, linked by a 15th-century building and dominates the Sèvre Niortaise valley.
The two donjons are the only remaining part of the castle. The castle was started by Henry II Plantagenet in the 12th century and completed by Richard the Lionheart. It was defended by a rectangular curtain wall and was damaged during the Wars of Religion. In the 18th century, the castle served as a prison.
The present keeps were the central point of a massive fortress. The southern keep is 28m tall, reinforced with turrets. The northern tower is slightly shorter at 23m. Both are flanked with circular turrets at the corners as well as semicircular buttresses. Each of the towers has a spiral staircase serving the upper floors. The Romanesque architecture is of a high quality with the dressed stones closely jointed.
