Winterthur is the premier museum of American decorative arts, with an unparalleled collection of nearly 90,000 objects made or used in America since 1640. The collection is displayed in the magnificent 175-room house, much as it was when the family of founder Henry Francis du Pont called it home. Winterthur is also 1,000 acres of protected meadows, woodlands, ponds, and waterways. The 60-acre garden, designed by du Pont, is among America’s best, with magnificent plantings and massive displays of color throughout the year. The graduate degree programs and extensive research library make Winterthur an important center for the study of American art and culture. Winterthur is open Tuesday through Sunday, 10am to 5pm. Located in Kennett Square. Expires November 30, 2023.
