The Keepers of the Flannan Isles

PlacesEilean Mòr, Outer Hebrides, Scotland · December 1900Mostly explained

On a remote Scottish island, the three keepers of a new lighthouse disappeared, and the light went dark.

What was reported

The Flannan Isles lighthouse on Eilean Mòr was lit in 1899. On 15 December 1900, a passing ship noticed it was dark. When the relief vessel Hesperus arrived on 26 December, the three keepers, James Ducat, Thomas Marshall and Donald MacArthur, were gone. The clock had stopped, and one set of oilskins was still on its peg.

Later tellings, including a famous poem, added an overturned chair and an untouched meal, details not in the original reports.

Explanations offered

The Northern Lighthouse Board's investigator found storm damage at the west landing, high above the sea, and concluded the men had been swept away by an unusually large wave while securing equipment. Why the third man left without his oilskins is still debated, and freak waves at that height are still discussed.
