This is the only state Capitol building I've been to multiple times, and I'm not even from Wisconsin (I just really love Madison). It's a fun way to spend a little or a lot of free time, especially if you're interested in history, architecture, art, or politics. You can take a tour or just wander around on your own, but be sure to check out the view from the outside terrace if it's open! The building itself is beautiful, and the location is very cool too - I love that as you're driving around the city, all the streets lead to the center so you can get a glimpse of the building as you drive.
