EILEAN MÒR — 1900 · Missing Person

The Vanishing of the Flannan Isles Lighthouse Keepers

UnsolvedSources: ALast updated: 14 October 2026

The lighthouse on Eilean Mòr, in the remote Flannan Isles off western Scotland, was first lit in December 1899. On 15 December 1900 a passing ship noted that the light was out. Because of bad weather the relief vessel Hesperus did not reach the island until 26 December. There was no sign of the three keepers, James Ducat, Thomas Marshall and Donald McArthur: the doors were shut, the lamps had been cleaned and refilled, the clock had stopped, and one set of oilskins was still in place. Heavy storm damage was found at the west landing. The official inquiry suggested the men had been swept away by a huge wave, but no bodies were ever found. Over time the case attracted exaggerated legends and invented logbook entries.
