Despite the Tromso Defence Museum being closed, it was on the route, so I dropped in just in case - it is across the road from the 'Tirpitz Battery' which appears to have been a German site in WW2. It is open to the public, but heavily overgrown with weeds. There are two 4.1-inch AA guns there (which were not from Tirpitz as they were a different model) - of the three that were apparently originally installed there, along with a variety of other artifacts strewn around amongst the weeds, including what appeared to be some fire control equipment, searchlights, a length of anchor chain etc, a motor boat (which may have been from Tirpitz) etc. Outside the actual museum was a Russian artillery piece, along with a mine and a torpedo.
