In 1989, in the midst of a raging storm off the Brittany coast, photographer Jean Guichard circled above the French lighthouse of la Jument (Le Phare de La Jument) in a helicopter, camera in hand to capture the tempest. Hearing the helicopter, keeper Theodore Malgorne came out to investigate but retreated quickly as a huge wave crashed into the lighthouse. This dramatic moment was captured by Guichard in a series of photographs.
In this clip from the BBC’s Coast series, Neil Oliver brings the two together to tell the story of that moment.
