The Chiang Kai-shek Memorial Hall in Taipei is one of those places you pretty much have to see if you’re a tourist. I guess you could skip it, but why? It’s seriously impressive, it’s right in the middle of the city, and it’s free to visit.
In what I have to assume is fallout from all of the terrorist shenanigans in Europe over the last few years, there are soldiers pretty much everywhere in Rome.
