For decades, the "Tiger Defence Line" from World War II, with its hidden stories, remained virtually invisible. The former canteen building has been transformed into a fascinating exhibition and reception area. There's plenty to do in the museum. For example, there's a treasure hunt for children, and you can book a guided tour on our website, which will lead you on a journey of discovery through various impressive structures. Prepare to be amazed! GPS Game: An informative GPS game has now been developed for families and groups of (young) adults to play inside and outside the museum. Collaboration and discovery are key. You can find all the information about the game at the museum's visitor center.
