It retains notable exterior and interior features such as a rounded corner entrance, a domed rotunda, marble wainscoting and original service windows. It also reflects the long effort to obtain a federal building for the town.","narrative":"Standing at the corner of State and Meadow streets in downtown Belvidere, this one-story post office of yellow brick and granite was dedicated on October 11, 1911. James Knox Taylor, Supervising Architect of the U.S. Treasury, designed it, and Rockford contractor E. Maffioli built it for $65,000. The Classical Revival building has a rounded corner entrance with a terra cotta pediment and cartouche, tall paired windows, brick pilasters, and a limestone balustrade above modillions. Inside, a domed rotunda with marble wainscoting and terrazzo floors leads to a lobby with original service windows, a large workroom, and a suspended lookout gallery for postal inspectors. The site was chosen after years of debate, with residents favoring a location between the river and the railroad, near the sewing machine factory. The building is recognized for its architecture and its well-preserved federal design. The post office moved out in 1997.","period_of_significance":"1911","architect_builder":"Taylor, James Knox, Supervising Architect U.S. Treasury; contractor E.
