Patton.","why_significant":"The nomination argues the building meets Criterion C as a locally significant, representative example of late 19th century commercial building design. It is described as one of the most intact such buildings in Monmouth, with original woodwork, cast iron storefront columns and stained glass windows found in no other commercial building in the city.","narrative":"Robert S. Patton, a longtime Warren County treasurer and Monmouth civic figure, built this three-story commercial block on the northwest side of the Public Square in 1891. Construction began in May and finished that December, at a cost of $15,000. The red brick building has two ground-floor storefronts flanking a central stair, limestone string courses, a stamped cast iron cornice reading \"Patton Block 1891,\" and cast iron columns made in Galesburg. Upper floors held offices and meeting rooms used by lodges, clubs and a business college, while the ground and third floors at times housed early movie theaters, including the Arrow and the Ada. The nomination highlights its integrity: the interior floor plan, pine woodwork, pocket doors, ceiling fans, light fixtures and original stained glass survive. No other commercial building in Monmouth is known to have used stained glass. Neighboring Public Square buildings have been altered more heavily, which supports its local significance for architecture.","period_of_significance":"1891","architect_builder":"Robert S.
