At each of the water passages that lead to New York Harbor – from the Narrows to Hell Gate, Ambrose Channel to the Race – disused forts stand on either shore, once guarding these entrances. In this virtual program, we will explore the history of coastal fortifications in New York from the Revolutionary War to World War II, examining the different eras of fort construction and the technological advancements that drove the changes in these forts’ shape, armament, and role over time. We will also look at how these forts have been repurposed today – as parks, schools, museums, and the last active military base in New York City.
