Before Ellis Island there was Castle Clinton. This historic Lower Manhattan destination once served as the first immigration stop for foreigners moving to the U.S., with some 8 million people passing through its doors between 1855 and 1890. And while the iconic brick building has had many lives—as a beer garden, theater and even an aquarium—today it serves as a national monument and museum.
Visitors tend to agree that while Castle Clinton holds a historic place in the story of New York City and is certainly worth checking out, the interior offers only a couple of displays that showcases stories of the Big Apple. Travelers heading to the Statue of Liberty can purchase tickets inside and make Castle Clinton part of the Battery Park experience.
