Awesome stop! And a strange sense of "back to the future", by walking into the 1960s-70s. In this bunker, you get the sense of what Tito and his generals were planning to do in the event of nuclear war - and that was to "hunker down" in a bunker, for up to 6 months, under a mountain. The engineers claimed this bunker would withstand a nuclear blast up to 20 kilotons. hmmmm .... having seen the insides and the "steel trap doors", I'm not so sure. But I am glad the world never had to find out.
