7. Battery Wall Remnant at Castle Clinton
Another piece of the colonial Battery Wall can be found at Castle Clinton. This piece has more dimension than the one-sided display in the South Ferry subway station. At Castle Clinton you will find an L-shaped bastion that researchers surmised likely projected outwards towards the water, creating a strategic place to position weapons that could be fired in several directions.
Castle Clinton was one of four forts constructed to prevent a British invasion in 1812. It also served as America’s first immigration station, prior to Ellis Island. Between 1855 to 1890 more than 8 million people entered the United States through Castle Clinton. Since then, the fort has served as a beer garden, theater, and public aquarium over the course of its life. Today it is a National Monument that you can visit.
