La Jument is the name of a lighthouse at the North-Eastern part of France, Brittany. The lighthouse is built on a rock (that is also called La Jument) about 300 metres from the coast of the island of Ushant, in the middle of the ocean. There is also an almost identical lighthouse about 3 kilometers to the North, the Nividic lighthouse. Together with the lighthouse Kreac'h , they are the 3 most famous lighthouses of the region.
The lighthouse became well-known in 1989, through a series of photographs taken by Jean Guichard during a storm and while the lighthouse keepers were stranded. Upon viewing the pictures, it would be easy to conclude that the man in the shots perished as a result of the wave. However, this is not true.
The lighthouse keepers had been waiting for a rescue helicopter, they heard the sound of Guichard's one, and one of them came out to investigate. As the enormous wave broke over the lighthouse, he was able to hastily retreat back inside.
