Exceptional museum with plenty of well presented displays. Layout is quite straightforward and not too confusing, with a bit of a walk through time, having displays and artifacts from different eras.
Decent stop for tourists as there is English signage as well as German. When we were there though, the museum did not allow payment with card, they needed Euros, make sure you have enough for the entrance fee. Entrance fee was 5 Euros per person at the time, quite cheap.
