Rock Lawn is a historic house in Garrison, New York, United States. It was built in the mid-19th century from a design by architect Richard Upjohn. In 1982 it was listed on the National Register of Historic Places along with its carriage house, designed by Stanford White and built around 1880. It is Upjohn's only house in the Italian villa style in the Hudson Highlands. Hamilton Fish II, a longtime member of the State Assembly and Putnam County's Republican Party chairman and de facto political boss, owned the house and lived there during the late 19th century; during that time sympathetic additions were made to the house by an unidentified architect. More recently it has been the home of Patty Hearst and her late husband Bernard Shaw. In the early 21st century it was renovated and remodeled. Buildings and grounds The house and carriage house are located on a lot in Garrison, an unincorporated hamlet of the town of Philipstown. It is located on Upper Station Road (County Route 14), approximately west of New York State Route 9D and east of the Hudson River, towards which the land slopes, then drops sharply, allowing a view across the river to the United States Military Academy at West Point, a National Historic Landmark. The landscape is largely cleared, with intermittent mature shade trees. Garrison's fire station is next door; a small Catholic church is across the road along with other large-lot houses. To the east and south are other residences. Among the other buildings and structures in the area are others listed on the National Register. At the junction of Upper Station and NY 9D are the Arts and Crafts Garrison Union Free School with the Moore House behind it, and St. Philip's Church in the Highlands, also designed by Upjohn. Down the hill to the east at the riverside, the small Garrison Landing Historic District is across the railroad tracks, just north of the Garrison station on Metro-North Railroad's Hudson Line. To the southeast, along Lower Station Road (County Route 12), is the Carpenter Gothic Wilson House. It completes the circuit back to NY 9D, at an intersection known as Garrison Four Corners, also the western terminus of short New York State Route 403. The Garrison Grist Mill Historic District occupies part of a local golf course, with the Mandeville House, a Dutch Colonial residence briefly remodeled by Upjohn, who lived
