Sea marks or beacons along the west coast of Jutland are tall, sculptural, three-legged wooden structures dating from 1884-85, and are part of a whole system of beacons that the coastal security of the time set up to improve maritime safety.
Of the original 23 sea marks, the remaining 11 beacons in Gl. Skagen, Løkken, Vigsø, Thorup, Stenbjerg, Vedersø Klit, Husby Klit, Årgab, Havrvig, Kærgård and Ringebjerge were listed as monuments by the Nature Agency in 1997.
The beacons are up to 12 meters high and the top part can be a circle, triangle, square or other easily recognizable figure. All beacons were marked as a location on the nautical charts so that the ship's captains could determine the exact position of the ship.
Nowadays, the beacons no longer have a function for shipping, but together with the rescue stations they are seen as cultural, historical and architectural landmarks in the West Jutland coastal landscape.
The term "Bake" or "Bavn" comes from the Middle Ages and was the name for a pile of wood that was lit as a signal fire on a hill.
