Nemours Estate
Delaware
Alfred I. du Pont's 1910 gift to his second wife: a 77-room French neoclassical chateau modeled on Versailles and the Petit Trianon, fronted by the longest formal allee of fountains in North America -- the 'American Versailles' story is an easy, vivid hook for road-trippers.
Why Roamward picked it
Visually spectacular grounds ideal for photo-driven social sharing and a GPS checkin at a fixed public entrance (1600 Rockland Road ticket house); rounds out the du Pont estate cluster with Hagley and Winterthur without overlapping existing DE content.
