7. Battery Wall Remnant at Castle Clinton

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.
