Boscobel is a historic house museum in Garrison, New York, overlooking the Hudson River. The house was built in the early 19th century by States Dyckman. It is considered an significant example of the Federal style of American architecture, augmented by Dyckman's extensive collection of period decorations and furniture. It was originally located in the Westchester County hamlet of Montrose. Restoration efforts in the mid-20th century moved it 15 miles (24 km) upriver to where it currently stands, on New York State Route 9D a mile south of the village of Cold Spring in Putnam County.
