Grey Towers -Gifford Pinchot Mansion, Milford, PA

Grey Towers National Historic Site, also known as Gifford Pinchot House or The Pinchot Institute, is located just off US 6 west of Milford, Pennsylvania, in Dingman Township. It is the ancestral home of Gifford Pinchot, first director of the United States Forest Service (USFS) and twice elected governor of Pennsylvania. The house, built in the style of a French château to reflect the Pinchot family's French origins, was designed by Richard Morris Hunt with some later work by Henry Edwards-Ficken. Situated on the hills above Milford, it overlooks the Delaware River. Pinchot grew up there and returned during the summers when his later life took him to Washington and Harrisburg. His wife, Cornelia Bryce Pinchot, made substantial changes to the interior of the home and gardens, in collaboration with several different architects, during that time. In 1963 his family donated it and the surrounding 102 acres (41 ha) to the Forest Service; it is the only U.S. National Historic Site managed by that agency.[5] Three years later the Department of the Interior designated it a National Historic Landmark. Today it is open to the public for tours and hiking on its trails; it is also home to the Pinchot Institute, which carries on his work in conservation.
