The United States Post Office and Courthouse in Rock Hill, constructed in 1931-32, is significant as an indicator of the population growth and commercial development of the city in the first third of the twentieth century. Its erection also reflects the rapid growth in Federal construction following the Public Buildings Act of 1926. The Post Office and Courthouse’s carefully composed classical exterior and richly ornamented lobby and courtroom, designed by the Supervising Architect’s Office of the Treasury Department, made the new Federal building the most accomplished piece of architecture in the city at the time of its construction. Well-maintained, and with only minor alterations, the Post Office and Courthouse is an important element in the fabric of the city’s central business district. Rectangular in plan, the three-story building has a low, pink granite podium, a rusticated limestone first floor, and two stories of yellow pressed brick in running bond, topped with a limestone entablature. On the south, east and west elevations, the parapet is composed of regularly spaced paneled limestone pedestals with turned limestone balusters between them. On the north elevation the parapet is continuous. Listed in the National Register January 21, 1988. - SCDAH
