The National Register of Historic Places is the official national list of historic properties in America worthy of preservation and is maintained by the National Park Service in the U.S. Department of the Interior. The State Register of Historic Places is Wisconsin's official listing of state properties determined to be significant to Wisconsin's heritage and is maintained by the Division of Historic Preservation at the Wisconsin Historical Society. Both listings include sites, buildings, structures, objects and districts that are significant in national, state or local history, architecture, archeology, engineering and culture. An historic district consists of contiguous properties that contribute to the distinctive characteristics of a type, period, or method of construction.
Several individual properties as well as five districts comprising hundreds of properties are listed in both the State Register and the National Register in Stoughton. Stoughton's districts include the East Side Historic District, Southwest Side Historic District, Northwest Side Historic District, East Park Historic District and the Main Street Historic District. Another proposed district, Depot Hill Historic District, has been formally determined eligible for listing in the State Register and National Register. It officially meets the requirements of the Register, but was not formally listed due to owner objections.
