There are many old German bunkers on the Jutlandish coastline. I’m not entirely certain why there are so many just outside the town of Løkken but I assume that the Germans thought that place to be especially vulnerable? Anyway, Most of them have been closed up and some of them look like the one below. There are however a few ones that you can enter and actually walk around in. They are, of course, very dark but I plan to bring the tripod on my next visit to get some photos of what they look on the inside in the tunnels. I’m really looking forward to that:)
