200 Hagley Creek Road · Wilmington, DE
Hagley covers 235 acres along Brandywine Creek where E.I. du Pont founded his black powder mills in 1802. In the historic powder yard you walk among the old mill buildings and watch demonstrations, then take a guided tour of Eleutherian Mills, the first du Pont family home in America. The Nation of Inventors exhibition displays more than 120 patent models from the 1800s. A shuttle links the main stops, and paths are gravel and uneven, so wear comfortable shoes.
