Castle Clinton National Monument
Open Now Free Today
Castle Clinton is a circular sandstone fort built between 1808 and 1811 to defend New York Harbor, which later served as an entertainment venue, immigration station (processing over 8 million immigrants between 1855 and 1890), and aquarium before becoming a National Monument in 1946. Located at the southern tip of Manhattan in Battery Park, it is one of New York's most storied landmarks.
