Sometimes when one is out walking one might stumble across a bit of history. In this case I did. During World War II Norway was occupied by German forces from 1940 until 1945. And like all occupying forces they did their best to protect themselves against both the inhabitants of the country and anyone who might attempt to help the occupied ones. In the area shown here they had both anti-aircraft artillery, ammunition depots and camps for Russian and Polish prisoners of war used for building army roads. And of course houses for their own troops. Here we can see the ruin of one such site. Exactly what is shown here I do not know, but most of it was removed after the war.
And the nature does its best to cover up the rest.
