Castle Clinton National Monument
A Fort with Many Lives at Manhattan’s Tip
Discover
At the southern tip of Manhattan, Castle Clinton has served as a harbor fort, an entertainment venue, an immigration depot, and an aquarium. More than eight million people entered the United States through Castle Garden, as it was then known, before the immigration center closed in 1890. Today the monument preserves this layered history beside New York Harbor.
