Castle Clinton National Monument

Castle Clinton National Monument, which has been previously known as Fort Clinton and Castle Garden, is a circular sandstone fort that sits in Manhattan's Battery Park. The fort was built in the very early 1800s and served as the country's first immigration station, operating even earlier than Ellis Island. An estimated eight million people came into the United States through Fort Clinton. Later, it was used as a beer garden, aquarium, exhibition hall, and theater.
