You don’t have to go to Oak Park to see Frank Lloyd Wright architecture. Sure, that might be the mecca for Wright enthusiasts, but is it worth sitting in Eisenhower Expressway traffic when you can admire the grand exterior and interior of one of Wright’s most famous works at the Frederick C. Robie House on the University of Chicago’s campus? (A 45-minute tour will cost you $20.) This house, built in 1909 and 1910, showcases Wright’s influential Prairie style. In fact, it’s arguably his finest example of it. The openness of the Midwest landscape inspired Wright to devise this airy, window-drenched residence, which would be his last Prairie-style creation — one that he humbly described as a “cornerstone of modern architecture.” 5757 S.
