Fodor's Expert Review State House

The gilded-dome state house, built in 1819, is the nation's oldest capitol building in which the legislature still uses the original chambers. From January through June, you can watch the two branches in action. The Senate has 24 members, and the House house has 400—a ratio of 1 representative per 3,500 residents (a world record). The visitor center coordinates guided and self-guided tours, bookable online or on-site, and displays history exhibits and paraphernalia from presidential primaries.
