Storm King Art Center, commonly referred to as Storm King and named after its proximity to Storm King Mountain, is an open-air museum located in Mountainville, New York. It contains what is perhaps the largest collection of contemporary outdoor sculptures in the United States. Founded in 1960 by Ralph E. Ogden as a museum for Hudson River School paintings, it soon evolved into a major sculpture venue with works from some of the most acclaimed artists of the 20th century. The site spans approximately 500 acres (200 ha; 0.78 sq mi), and is located about a one-hour drive north of Manhattan.[2]
