Beautiful building that once housed the Federal workers who processed the pensions for Civil War veterans (North only)
This is a really cool building. Each summer they have a them, this year is called "Hive". If you get a chance, go check it out!
They have a kids building zone where kids can build with oversized blocks, etc. If you plan on going you should get tickets in advance on their website. The museum itself is also very cool.
