Absolutely worth a visit especially if you are historically interested in military. To see the Cold War instruments compared to what we can today is interesting.

I can highly recommend to take the guided tour, it is worth every penny. In our case the guide did it completely in english. He told us that he adopts language to the people taking the tour.

Very interesting to see. Quite unfortunate that they only offer tours in Danish (English tour available via audio guide). Guide did answer questions in English though and sounded very good in Danish ?
