In the early 1900s, Frank Lloyd Wright transformed a small midwestern prairie community into one of the world’s most important architectural destinations. Mason City, Iowa, became home to his City National Bank and Park Inn—the last surviving Wright hotel. In addition, his prototype Stockman House helped launch the Prairie School architectural style. Soon after, architect Walter Burley Griffin followed in Wright’s footsteps, designing a cluster of Prairie School homes in the Rock Crest/Rock Glen neighborhood. Design historian Roy Behrens leads the way through Mason City’s historic development from the Industrial Revolution to the modern era of Frank Lloyd Wright.
