Military Museum

You probably wouldn't think that Lisbon's Military Museum would be anything special. Nobody ever talks about it, and it hardly appears in travel guides. You'll never find it on a "Best of Lisbon" list. So when we showed up on a lazy day during which we had nothing else to do, our expectations were low. But this turned out to be a major surprise; in fact, it was one of the coolest museums we saw during our time in the city.
