Winterthur, the palatial residence of collector and horticulturist Henry Francis du Pont, is one of the most impressive surviving country estates in America. Located in Wilmington, the mansion is open for tours of all kinds throughout the year. The 60-acre spread provides a vantage point of both historic farmland and the kind of formal gardens that were typical of the 19th century. Exploring the famous children's garden, Enchanted Woods, is a delight for all.
The Kalmar Nyckel, known as the Tall Ship of Delaware, was the Swedish-sailed vessel that brought the first permanent settlers of European descent to the Delaware Valley in 1638. The life-size, seaworthy replica of the ship resides in Wilmington and offers tours of the ship and shipyard, sailing events and charter trips to those willing to try out their sea legs.
