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.
