I love the architecture of the Capitol Building, inside and out. If you love it as much as I do, you’ll be happy to know that you can tour the Capitol Building for free, provided they aren’t closed for special events. During off-peak season, it’s easy to just walk in and join a tour slot. I suggest advance online booking if you’re visiting in the summer.
Headsets, which are handed out after the obligatory welcome film, is how your tour guide will talk to you about the Capitol Building’s standout features, (as well as call to group members who straggle a little too long at one spot for the tour guide’s comfort.)
During the tour, don’t be surprised to find your gaze focused upwards more than half the time.
