The John Archibald Campbell United States Courthouse, also known as the United States Court House and Custom House, is a historic courthouse and former custom house in Mobile, Alabama. It was completed in 1935. An addition to the west was completed in 1940. It was added to the National Register of Historic Places on October 8, 2008.The courthouse was designed to house the United States District Court for the Southern District of Alabama and the United States Customs Service. The customs service later vacated the building and the courts expanded into their space. This building replaced an earlier antebellum-era structure that served the city and region.The building is built in an austere blending of the Renaissance Revival and Art Deco styles. The façade is clad in white limestone with a granite base.HistoryConstruction of the John Archibald Campbell United States Courthouse began in 1934 on the north half of a city block facing Saint Joseph Street, then adjacent to the 1916 United States Post Office building. The block is encircled by Saint Joseph, Saint Louis, North Conception, and Saint Michael streets. Having a monumental scale and finer materials than most of the surrounding structures, this ensemble created a strong presence for the federal government in downtown Mobile.
