Cold Spring is a village in the town of Philipstown in Putnam County. The population was 1,948 (2016). It borders the smaller village of Nelsonville. The central area of the village is on the National Register of Historic Places as the Cold Spring Historic District due to its many well-preserved 19th-century buildings, constructed to accommodate workers at the nearby West Point Foundry (itself a Registered Historic Place today). The town is the birthplace of General Gouverneur K. Warren, who was an important figure in the Union Army during the Civil War. The village, located in the Hudson Highlands, sits across the river from West Point, at the deepest point of the Hudson River. Cold Spring serves as a weekend getaway for residents of New York City.
