Completed in 1858, this Renaissance Revival–Italian Palace–style building in Georgetown, Washington, D.C., was designed by Ammi B. Young, the Supervising Architect of the United States Treasury, during 1856–57. The main block measures 61 by 46 feet with additions extending to the north and east, and is topped by a low seamed-metal roof. Originally serving dual federal purposes—a branch post office on the first floor and the Customs Service on the second—the structure cost $55,468 to build. After the customs operation relocated in 1967, a small post office branch remained. Listed on the National Register of Historic Places in 1971, the building is also a contributing structure within the Georgetown Historic District.
