During the Second World War, the Skagen area was heavily fortified and you find traces everywhere from the occupation (1940-1945). In the Råbjerg Mile area the Germans had many concrete bunkers at the small village of Kandestederne to the West and in the Bunken Dune Plantation to the East you'll find a fortification called "Sperrbatterie Aalbaek Bucht". The fortification had 13 concrete bunkers with heavy artillery and during the war more than 200 soldiers were posted there. Today it a bit eerie walking in the old network of German trails.
