Seoul’s War Memorial Museum is a massive complex that can easily eat up a history buff’s whole day. The big-ticket items—tanks, planes, missiles—are outside; inside is a complete history of military actions in Korea. One really cool thing is a replica of Admiral Sun-shin’s “turtle warships,” ironclad fighting boats used in the 16th century. The bulk of the place is taken up with the Korean War, with tons of films and photos that can get a little overwhelming for the unprepared. Korea was a suburb of hell from 1950 to 1953, and no punches are pulled here in showing just what it was like. It might be best to head for a park after your visit, to decompress and remember that it’s always business as usual for the trees.
