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 and twice elected governor of Pennsylvania.
The mansion itself is a three-story L-shaped fieldstone chateau. Conical roofed towers at three of the corners give the property its name. A service wing juts out from the fourth corner. As originally built it contained 43 rooms, with the first floor featuring a large entrance hall, billiard room, dining room, library and sitting room. Bedrooms were located on the second floor, with more on the third floor plus storage spaces and children’s playrooms.
The house boasts a number of outbuildings. On the 303 acres (123 ha) of the combined parcels that made up the original estate, there are 48 total buildings, structures and sites, all but eight of which are considered contributing to its historic value. These include nearby cottages known as the Letter and Bait Boxes, a unique outdoor dining facility called the Finger Bowl, a Forester’s Cottage used as a residence by the Pinchot descendants, an open-air theatre, the former Yale School of Forestry’s summer school, and a white pine plantation established by Gifford Pinchot.
