Foula: Edge of the World
The ancient Romans thought Foula was Ultima Thule, a place beyond the borders of the known world. Michael Powell used the island as a stand-in for St Kilda in his 1937 film The Edge of the World. All of which is to say that Foula feels pretty remote.
You’ll see Foula described as the UK’s most remote inhabited island, but that’s not technically true (geographically, Fair Isle is more remote). But, according to one of the crew on the tiny, exceptionally rolly, boat that travels between Waas and Foula, the island can claim the title most isolated inhabited UK island. (Pop. 30)
