Built to keep people out; now welcomes millions in.
Located at the southern tip of Manhattan Island, Castle Clinton stands where New York City began, and represents not only the city’s growth, but the growth of a nation. Initially intended to prevent a British invasion in 1812, the fortification has transformed over the years to welcome theatergoers, immigrants, sightseers, and now, millions of visitors to New York Harbor.

Castle Clinton National Monument is open year round and is located in Battery Park. Admission to the site is free and we are open every day except Christmas Day (December 25). Visitors are welcome to explore the open air fort as well as visiting our exhibits. Junior Ranger programs are available for kids and our Eastern National bookstore offers a wide variety of books and memorabilia.

Castle Clinton National Monument is also the ticket office for Statue Cruises the official cruise that take visitors to the Statue of Liberty and Ellis Island.

Pets are not permitted on the premises. Service animals are the only allowable exception.
