Hagley Museum & Library is where the du Pont story begins. Our museum is the site of the gunpowder works founded by E.I. du Pont in 1802 along the banks of the Brandywine River. The 235 Acre campus includes restored mills, a workers' hill, and the ancestral home and gardens of the du Pont family. Visit for two hours or for a full day; watch demonstrations in the machine shop, interact with interpreters, browse through exhibits, stroll through formal French gardens, or enjoy a meal or snack at the Belin House Organic cafe. Explore the riverside landscape that was once roaring with industry. Hagley is part of the Blue Star Museums program. Free admission is given to military in the Army, Navy, Air Force, Marines, Coast Guard, National Guard, and Reserve members with valid ID from Memorial Day, May 28, 2012 through Labor Day, September 3, 2012.
