Bellevue State Park, a 331-acre park near Wilmington overlooking the Delaware River, preserves the layered history of a former private estate. Beginning with Hanson Robinson’s 1855 Gothic Revival Woolton Hall, the property evolved under C. R. Griggs and William du Pont Sr. before William du Pont Jr. remade the mansion into Bellevue Hall and expanded the grounds with major equestrian and recreational facilities. After du Pont’s death in 1965, Delaware bought the estate in 1976 and opened it to the public. The park still reflects its estate origins while also offering recreation and preserving other historic sites tied to Delaware’s architectural and landscape history.
