There are only a few places in the world where visitors can gain a hands-on experience of the interior of a submarine which is ready for action. Aalborg Marinemuseum is one such place. The submarine SPRINGEREN is an unusual attraction, which together with the rest of the museum has been visited by hundreds of thousands of visitors since His Royal Highness Prince Henrik opened the museum on 24 May 1992. Since then, the collection has been extended almost week by week.
