Argyll & Dunbartonshire: About 4.5 miles east of Kilmelford, on minor road east of A816 at Kilmelford, on small island at west end of Loch Avich.

Ruin or site   NM 916137   OS: 55   PA35 1HJ

OPEN: Car parking and picnic area by the island.

On Innis Luina, a heavily wooded island in the picturesque loch, little survives of Caisteal na Nighinn Ruaidhe (‘castle of the red-haired girl’), a 13th-century castle of enclosure and hall house.

This was a property of the Campbells. The name is said to come from Bridget, heiress to the lands around Loch Avich, who married a Campbell around 1200.

An alternative tale is that, just after the building was first constructed, a red-haired servant at the castle was thrown to her death from the walls after discovering a plot to murder the mason. Her angry ghost then plagued the castle.
