Built 1856-1859 as the U.S. Customs House and Post Office, it now serves as Petersburg City Hall.","why_significant":"The building is presented as a superb example of Italian Renaissance Revival architecture designed by federal architect Ammi B. Young, then Supervising Architect of the U.S. Treasury. It symbolizes federal authority and the city's antebellum prosperity. It also served as Confederate Army headquarters and a signal station during the siege of Petersburg.","narrative":"Petersburg City Hall, at the corner of Tabb and Union Streets, began as a federal Customs House and Post Office built between 1856 and 1859. Ammi B. Young, Supervising Architect of the U.S. Treasury, designed it in the Italian Renaissance Revival style. The three-story building is faced in Dinwiddie granite over brick walls, with arcaded first-floor windows, pedimented second-floor windows and a large denticulated cornice. It reflected both federal authority and the prosperity of a city whose tobacco, cotton and iron industries were expanding in the 1850s. The building served the federal government only briefly. During the Civil War it became Confederate Army headquarters and a signal station overlooking the fighting, and on April 3, 1865, Union soldiers raised the U.S. flag over it. A three-bay addition that duplicated the exterior was built on the south side in 1908-1910. The Post Office moved out by 1936, and in 1938 the building became city hall.","period_of_significance":"1856-9; addition 1908-10","architect_builder":"Ammi B.
