Bunkermuseum Wurzenpass

High on the Wurzen Pass, a Cold War defensive position that stayed secret for decades is now open to visitors. Seven bunkers, linked in part by passages and tunnel-like fighting positions, can be explored in their original state. A collection on the subject adds context, and you can even ride along in a tank. It is described as Austria's largest connected barrier position and has been open to the public since 2005, generally from mid-May to the end of October.
