If you’ve ever had a picnic in Battery Park or taken a trip to the Statue of Liberty you’ve probably walked through Castle Clinton, a medieval-looking fortress dating back to 1808 that sits by the water’s edge. This structure, now used as a ticket office and information center for tourists heading to Liberty Island, has been through almost as many changes as New York City itself and was nearly demolished on six different occasions, only to be rescued and restored by the National Park Service in 1946. A remnant of the City’s colonial roots, the building has been involved in military, artistic, and immigration-oriented initiatives since it’s construction, serving an impressively diverse variety of roles during its 207 years of existence. Like the Museum at Eldridge Street, the now restored building pays homage to the stories of the people who passed through its doors during each stage of its evolution, reflecting the ever-changing nature of the city and the people who inhabit it.
