Shuna Island[3] or simply Shuna is an island in Loch Linnhe, offshore from Appin, in Argyll and Bute, Scotland. The island is approximately 2km (01miles) long and 1frac=8NaNfrac=8 wide, and extends to some 1550NaN0 in total. The island is characterised by a table topped hill at its southern end.[4] The name Shuna is probably derived from the Norse, for "sea island".[1] The island is separated from Appin by the Sound of Shuna.
Shuna is recorded in a late 16th-century document as belonging to John Stewart, the Laird of Appin.[2] He may have built Castle Shuna, a small tower-house, which is now in ruins and lies at the south end.[5] In the 18th century, Shuna Farmhouse replaced Castle Shuna as the residence on the island: it is a Category B listed traditional farmhouse dating from the 1740s. Opposite Castle Shuna, at the head of Loch Laich, is the island fortress of Castle Stalker, also historically a possession of the Stewarts of Appin.
The island forms part of the Lynn of Lorn National Scenic Area, one of 40 in Scotland.[6]
In 2012 the island was placed on sale via agents Savills for £1.85 million.[7]
