This was a German coastal fort during ww2, located at Spåkenes, Djupvik, Kåfjord Municipality in Northern Norway.
After the war the German facilities was blown to bits, and during the German retreat the whole county was burned and the people evacuated.
To me it looks like the aurora formed a skull in the sky, however you want to interpret this is up to you, but I think it adds to the image.
