Shift change at the Kéréon lighthouse, on Snapping Stone Reef (récif de Men Tensel), Breton, France.

In Brittany, an isolated, sea-bound lighthouse is called a ‘Hell.’ Le Kéréon was the last French hell to be automated, in January, 2004. Not sure why there is a shift change at an automated lighthouse. Maybe Paul Cranford will know.
