Many visitors to the Charleston area are keenly aware of the famous fort that sits in the Charleston harbor. Fort Sumter played an important role in the American Civil War, as did Fort Moultrie over on Sullivans Island. But most people, even some locals, aren’t exactly aware of a third fort used during that same war; a fort also located in the harbor and whose ruins now wither away under the constant laps of the sea and passage of time. Over the years, Castle Pinckney, located on Shutes Folly in the harbor, would be used for a number of purposes. Today, it’s the only sea-bound abandoned prison in South Carolina.
