Hagley Museum & Winterthur
Any visit to the Brandywine Valley should begin at Hagley — what you discover here will put your entire trip into context. It is here that the du Pont family first settled in America, built their first home, and began the black powder manufacturing business that became the foundation for all the other du Pont enterprises in the world. The continuing legacy of Hagley and the early family can then be explored in the splendor of Winterthur, Longwood Gardens and Nemours.
