The Metropolitan Block is a commercial building along North Main Street in downtown Lima, Ohio. Built in 1890 at the middle of Lima's petroleum boom, the five-story building is a Victorian version of the Romanesque Revival style. Built primarily of brick, the block includes many stone details throughout its exterior, supporting elements of cast iron on the first floor, and the original glass windows of its storefronts. Among the building's decorative elements are transom windows of lavender-colored glass above the entrances, awnings of canvas covering the sidewalks around the building, and turrets at the top of the facade.
