Knights of Columbus Building, 202-204 South Federal Avenue, Mason City, Cerro Gordo County, IA
Significance: The building exhibits the simple lines of the so-called "Commercial Style." It shows a Prairie School influence with emphasis on strong horizontal lines and exterior usage of brick and terra-cotta. The decorative terra-cotta work is reminiscent of Louis Sullivan inspired ornamentation. The structure was an important mixed-use building in Mason City and the first to be originally built as a lodge hall for the Knights of Columbus in Mason City, Iowa.
