Island of Stroma

Stroma is an uninhabited island in the Pentland Firth, between Orkney and the mainland of Scotland. It forms part of the civil parish of Canisbay in Caithness, in the council area of Highland. The name comes from the Old Norse Straumey, meaning "island in the current".

Ancient stone structures testify to the presence of Stroma's earliest residents, while a Norse presence around 900–1,000 years ago is recorded in the Orkneyinga Saga. It has been politically united with Caithness since at least the 15th century. Although Stroma lies only a few miles off the Scottish coast, the savage weather and ferociously strong tides of the Pentland Firth meant that the island's inhabitants were very isolated, causing them to be largely self-sufficient, trading agricultural produce and fish with the mainlanders.

Most of the islanders were fishermen and crofters; some also worked as maritime pilots to guide vessels through the treacherous waters of the Pentland Firth. The tides and currents meant that shipwrecks were frequent—the most recent occurring in 1993—and salvage provided an additional though often illegal supplement to the islanders' incomes. A lighthouse was built on Stroma in 1890 and still operates under automation.

Stroma is now abandoned, with the houses of its former inhabitants unoccupied and falling into ruin. Its population fell gradually through the first half of the 20th century as inhabitants drifted away to seek opportunities elsewhere, as economic problems and Stroma's isolation made life on the island increasingly unsupportable. From an all-time peak of 375 people in 1901, the population fell to just 12 by 1961 and the last islanders left at the end of the following year. Stroma's final abandonment came in 1997 when the lighthouse keepers and their families departed. The island is now owned by one of its former inhabitants, who uses it to graze sheep.
