The Arctic convoys were a vital supply line for Russia during WWII; these merchant ships escorted by Allied warships brought supplies into the northern ports through a gauntlet of German ships and submarines. Many left from Loch Ewe, and this volunteer project tells some of the stories of those tough trips. It's fascinating; there's also a small shop.
It's on the A832, 12 miles north of Gairloch. Winter opening hours may vary according to volunteer availability.
