Eleutherian Mills

From 1802 to 1921, Eleutherian Mills was a gunpowder mill site used for the manufacture of explosives by the Du Pont family business. The name also refers to the house on the hill above the mills, which was the first Du Pont family home in America. The business was founded by Eleuthère Irénée du Pont. In 1952, the site became an outdoor museum and the Hagley Museum and Library was founded.
