Castle Tioram at Dorlin, Ardnamurchan

Castle Tioram (pronounced "Chee-rum" meaning "dry castle") is a ruined castle which sits on the island Eilean Tioram in Loch Moidart.  Though hidden from the sea, the castle and its island rock controls access to Loch Sheil.

The castle - a listed building and scheduled ancient monument - is the traditional seat of the Clan MacDonald.  Castle Tioram was seized by Government forces around 1692 when the  then 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 the castle, purportedly to keep it out of the hands of the Goverment forces. It has been unoccupied since that time. 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.

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 northwest curtain wall in 2000.

Controversial proposals to restore the castle by the new owners, Anta Estates, were announced in 1997 and received planning consent from Highland Council. This included the creation of a clan centre/museum, domestic apartments, and public access. However, Historic Scotland refused Scheduled Monument Consent - a decision upheld after a local public inquiry.

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.
