For the first time in 85 years, an island off the west coast of Scotland has listed for $1.9 million.

Known as Torsa Island, one of the Slate Islands that together form an archipelago, it spans 270 acres.

One of the historical features of the island is the ruined Casteal nan Con (the Dogs’ Castle), located to the northeast of the island.

Situated on a rocky platform, the tower house was held by Clan Maclean — a Highlands Scottish clan. They are one of the oldest clans in the Highlands and owned large tracts of land in Argyll.

Torsa’s name is of Norse origin, roughly translated as “Thor’s Island,” with the island steeped in Clan history.

The island boasts a three-bedroom period farmhouse, which boasts view of the sea and has many species of wildlife that inhabit the island, including sea eagles, blue hare, roe deer and otters.

The listing also notes that several wild birds of interest to lure in sports enthusiasts include snipe, woodcock, duck, and geese.

“Torsa is something of a rarity as a Scottish island, offering the opportunity to own an idyllic island with complete tranquillity and privacy that is also readily accessible to the Scottish mainland,” the listing says.

Currently, the land is farmed for cattle and sheep — and Torsa Farmhouse is currently managed as a successful holiday business.

Adjacent to the farmhouse is a range of traditional stone farm buildings, which have the potential for re-development into further residential accommodations, the listing notes.

A sheltered anchorage for motorboats and yachts is found in Ardinamir Bay, to the south of the island, and Torsa is just a short trip by sea from Ellenabeich on the Isle of Seil — connected by a historic bridge to the mainland.

“This idyllic Scottish island surrounded by stunning West Coast scenery and sheltered sailing waters could be a dream haven for a buyer seeking peace and solitude, but there is also the option of taking on an established holiday let business if desired,” Luke French, for Savills, told The Post in a statement.
