Castle Clinton National Monument


Located at the southern tip of the island of Manhattan, Castle Clinton represents not only the growth of New York City, but the growth of a nation. First intended to keep out a British invasion in 1812, the Castle has transformed over the years to welcome theater goers, immigrants, sightseers, and now, millions of visitors to New York Harbor.

Originally built to be a fort for the War of 1812 Castle Clinton has seen many changes over the years. After it was a fort it became an opera house from 1840-1855 and renamed Castle Garden. An immigration station operated here between 1855-1890. After Ellis Island opened in 1892 the building was transformed into the New York City Aquarium from 1896-1941.

Castle Clinton is also a place for education and entertainment, offering guided tours, an exhibit room displaying dioramas of Castle Clinton during three key periods in its history, the Eastern National Bookstore, and the annual 'Music at Castle Clinton' concert series.
