National Parks of New York Harbor is the name of an office of the National Park Service that coordinates administration of eleven NPS sites that include 23 unique destinations located in the New York metropolitan area. National Parks of New York Harbor was formed in 2003 and administers properties ranging from the Statue of Liberty National Monument in New York Harbor to Gateway National Recreation Area in several locations and Saint Paul's Church National Historic Site in Mount Vernon, New York. Despite its name, technically the office does not oversee any national parks, but rather national monuments, national memorials, national historic sites, and a large national recreation area.[1] Properties overseen by the office make up 27,000 acres (110 km2) and attract more than 12 million visitors each year. They are served by a visitor's center at Federal Hall National Memorial.
