||Established by Congress in 1966, the National Register of Historic Places is the nation's official list of significant historic properties. Each state has a historic preservation office, which is responsible for nominating buildings, sites, districts, etc. to the Register. In Louisiana, the Division of Historic Preservation administers this program and the site for the Louisiana National Register of Historic Places. On the Louisiana site a researcher will find an interactive map of current Louisiana historic places, informative videos, links to other sites of interest and more.
