Sværholtklubben

[6][7] The name Sværholtklubben derives from the nearby abandoned village of Sværholt, positioned just south of the mountain.

[8][9][10] During World War II, Sværholtklubben served as a strategic defense location for the Germans.

In May 1942, they established the Heeres Küsten Batterie Svaerholtklubben 1/971, which included six 14.5 centimetres (5.7 in) guns capable of firing at targets up to 19 kilometres (12 mi) away.

[14] The cliff's slanted shale layers create a series of ledges that ascend into the mountainside, providing an ideal nesting environment for tens of thousands of birds.

[10][15] Due to its large amount of avian life and ecological importance, the bird cliff and the surrounding marine area were designated as the Sværholtklubben Nature Reserve in 1983.
