Marin County Civic Center, just n. of San Rafael off US 101, was the last major project of renowned architect Frank Lloyd Wright. The 140 landscaped acres include fairgrounds, theaters, exhibit halls and a lagoon. The civic center itself is divided into two wings—the administrative offices and the Hall of Justice—joined by an 80-foot dome. Both are included on a 1.5-hour, docent-led guided tour.
