Finlaggan Castle (, ), also known as
Eilean Mòr Castle, is a ruined fortified house located on the isle of Eilean Mòr on Loch Finlaggan. It was once a residence and stronghold of
Lord of the Isles and
Clan Donald. In the first half of the 7th century, a monastic community was established on Eilean Mòr, the largest of the three islands in the loch. This was either dedicated to or possibly founded by St Findlugan, an Irish monk and a contemporary of St Columba. St Findlugan is officially venerated as a saint in the
Roman Catholic Church and
Eastern Orthodox Church. The ruins we see today are from a castle built in the 13th century, with masonry walls. An earlier construction, likely timber, was erected in 1138 by
Somerled, Lord of Argyll, Kintyre, and Lorne, the first "Lord of the Isles". The 12th century building might have been constructed on the remains of an earlier Iron Age fort. The Lords of the Isles used the fortress as a principal court and meeting place of their clan chiefs. Iain Mòr MacDonald,
3rd of Dunnyveg, and his son Iain Cathanach MacDonald were taken prisoner at Finlaggan Castle, through the deception of
MacIain of Ardnamurchan, for the hanging and execution of the governor of
Dunaverty Castle and were later tried and hanged on the
Burgh Muir,
Edinburgh. In 1541 Finlaggan was held from the Crown by Donald MacGilleasbuig. The castle appears to have been demolished in the 15th–16th centuries. ==Footnotes==
