Welcome to Idaho’s Capitol for Kids! Idaho’s Capitol is located in the heart of downtown Boise, but no matter where you live in the state, this big, beautiful building belongs to you. That’s right: All 250,000 square feet of it – from the top of the dome (where I sit) to the bottom of the underground wings. This site will help you learn everything there is to know about your Capitol. Watch videos, play games, take a tour, have fun and, by all means, come and visit me soon!
