A restored mid-19th-century mill community on 235 landscaped acres along the Brandywine River, the Hagley Museum and Library provides an enlightening look at the development of early industrial America. This is the site of the first of the du Pont family's black-powder mills, family estate and gardens. Live demonstrations depict the dangerous work of the early explosives industry. "Du Pont Science and Discovery" traces the company's evolution and displays a NASCAR car
and a space suit. Admission includes a narrated bus tour through the powder yards with stops at Eleutherian Mills, the 1803 Georgian-style home furnished by five generations of du Ponts; Workers' Hill, where costumed interpreters describe the life of a typical mill worker; demonstrations in a machine shop and power yard; and a French Renaissance–style garden. Allow about two hours for your visit. The coffee shop is open for lunch year-round.
