About National Register Listings
The National Register of Historic Places is the official list of the Nation’s historic places worthy of preservation. Authorized by the National Historic Preservation Act of 1966, the National Park Service’s National Register of Historic Places is part of a national program to coordinate and support public and private efforts to identify, evaluate, and protect America’s historic and archeological resources.
In the 19th century, the District of Delaware was known for its production of gunpowder, and several gunpowder mills were established in the region. One of the most famous mills was the Hagley Powder Mills, which were founded by the DuPont family in the early 1800s. The mills were a major supplier of gunpowder to the U.S. military during the Civil War.
