The Deutsches Panzermuseum in Munster is very recommendable. The tanks and vehicles are out there to be freely walked around or touched. The collection is very complete and everything is in good shape. It exhibition shows the development of the German tanks and vehicles in chronological order. Most of these tanks are unique in the world, but most impressive are by far the Jagdpanther, the Köningstiger, and for the grand finale of WW2 tanks the absolutely huge “Sturmtiger” a.k.a. “Sturmmörser”.
