Fort Delaware and the Ghosts of the Civil War
On an island in the Delaware River sits a granite fortress that served as a Union prison — and, some insist, never quite let its dead leave.

On a low island in the Delaware River stands a grim granite fortress with a heavy past. Fort Delaware was built to defend the approach to Philadelphia and Wilmington, but it earned its lasting reputation during the Civil War, when it served as a prison camp holding thousands of Confederate soldiers in harsh conditions.
The suffering there was real and severe. Overcrowding, disease, and exposure claimed the lives of many prisoners, and the island's history is inseparable from that toll. The fort's cold stone corridors have never entirely shed the weight of what happened within them.
That history has made the site a magnet for ghost stories. Visitors and staff trade accounts of unexplained sounds and sightings, and the fort leans into its haunted reputation with evening tours that draw crowds each autumn.
Beneath the spectacle lies a serious place of memory. Whatever one makes of the ghost stories, Fort Delaware preserves a hard chapter of the war and honors the men who died far from home on a small island in the river.
