Fill up the tank for a road trip built around some of the famed architect’s greatest hits on a journey spanning from Rockford, a city on the rise, down to the state capital of Springfield. Illinois introduced its Frank Lloyd Wright Trail last spring, a year after Wisconsin rolled out its own version. The Prairie State’s iteration consists of 13 Wright sites open to the public, including his home and studio in Oak Park, a bank in Dwight, a chapel in Belvidere and a farmhouse in Hampshire. Visit the state’s tourism website, EnjoyIllinois.com, to find self-guided itineraries pegged to the trail, like a 110-mile trip from Chicago to Rockford, where you can tour the only building the prolific Wright ever designed for a client with a disability. While you’re in town, get some coffee at Rockford Roasting, food at Social Urban Bar & Restaurant and beer at Prairie Street Brewing Co., on the banks of the Rock River. On the southern end of the trail in Springfield is the stunning (and free) Dana-Thomas House, a showcase of Wright-designed furniture — more than 100 original pieces — and an even bigger inventory of his art glass windows, doors and light fixtures. Another abode worth visiting in the capital: the recently restored Governor’s Mansion, open daily for public tours.
