The Battery is one of New York City's oldest public open spaces. Dutch settlers landed here in 1623 and established New Amsterdam. Now the Battery is truly the cradle of New York history, the front lawn of the Downtown district, and a hub of harbor access and cultural tourism. Over four million people, including residents, office workers, school groups, and tourists from around the world annually visit the park and its major landmark, Castle Clinton National Monument. Encompassing 25 acres of waterfront parkland, the Battery is the largest public open space Downtown. Over 280,000 people work within walking distance of the Battery, and over 36,000 residents live in the surrounding area. The Battery has the potential to serve as a major neighborhood amenity, with expansive lawns, overarching shade trees, vast perennial gardens, waterfront promenades, and cultural programs including summertime open-air concerts.
