Because of continuing flood damage assessment, certain areas of Hagley are currently closed to the public. Visit the Hours & Tickets page (link) for details.

Hagley is the former industrial site of the original black powder works of the DuPont Company, founded in Delaware in 1802 and powered by the natural resources that surrounded it. A visit to Hagley can last from ninety minutes to a full day. The museum offers free parking, picnic areas, and transportation to three major interpretive areas.
