The waters located between the western coast and Ushant island form the Iroise Sea.
Over thirty ships were lost in this region between 1888 and 1904.
La Jument became well known in 1989, through a series of photographs taken by Jean Guichard.
Lighthouse keeper Theodore Malgorn decided to take refuge up in the lantern room while waiting to be rescued.
Guichard wanted to fly over the Iroise Sea despite extremely dangerous flying conditions.
The inside, however, is another story.
Indeed, Phare de Kereon was nicknamed “The Palace” because of its lavishly decorated interior.
The lighthouse is built of granite with a base diameter of 4 meters and stands 48 meters tall.
Today the lighthouse is powered by batteries, and two wind-powered generators.
The guards, who were still responsible for proper operation and maintenance, left the lighthouse in 2004.
Since then, the lighthouse is fully automated.
