Castle Clinton National Monument
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.
Permanent Collection
The fort itself is the primary exhibit, with interpretive displays inside the circular walls tracing its transformation from military fortification to entertainment garden, immigrant landing depot, and aquarium. Rangers provide historical programs on the fort's 200-year role in New York City's history.
