It takes in the village of Cooperstown and parts of the towns of Otsego, Springfield and Middlefield, with resources dating from about 1785 to 1949.","why_significant":"The nomination argues that the lake and its ridgeline-framed surroundings have sustained a consistent pattern of agriculture, estates, village life and summer recreation for over two hundred years. It ties the area to James Fenimore Cooper and his Leatherstocking Tales, which drew tourists, and to the Clark family, whose land purchases preserved the landscape that appealed to nineteenth-century visitors. The district is recommended as significant nationally and locally.","narrative":"Otsego Lake, a long, narrow glacial lake in Otsego County, New York, anchors a 15,000-acre district that includes the village of Cooperstown and parts of three surrounding towns. Ridgelines on all sides frame the landscape, and the area contains farmsteads, lakeside estates, camps, docks, boathouses, gardens, monuments, museums and a dense village center. Land patterns trace to eighteenth-century patent surveys, with long strip lots running from shore to ridge on the west and north. The area is tied to novelist James Fenimore Cooper, whose Leatherstocking Tales and residence drew summer visitors from the mid-nineteenth century. Resort development was slow because of poor roads and limited lodging. The Clark family later bought and reforested much of the east shore and consolidated farms and estates, keeping the scenery that attracted early tourists. The district replaces the earlier Cooperstown Historic District listing and includes Hyde Hall, an early nineteenth-century estate house, with a period of significance from about 1785 to 1949.","period_of_significance":"c1785-1949","architect_builder":null,"architectural_style":"Early Republic; Mid-19th Century; Late Victorian; Late 19th and 20th Century Revivals and American Movements","criteria":[],"status_note":"Historic and current uses are the same: domestic, recreation, agriculture and landscape.
