A vivid look at how the other half lived, the Louis XVI–style home reflects the Alfred du Pont family's preference for fine automobiles, European antiques, and formal French gardens. Elegant design details are precise in each of the mansion's 102 rooms as well as the 300-acre grounds. The home is open for guided tours only and reservations are essential. Visitors must be age 12 and older.
