Haunted Places in Delaware: A Prison Island, a Haunted Governor's Mansion, and the Catman

Fort Delaware is supposed to be a quiet state park you reach by ferry, but the place has a talent for turning “history” into something that feels way too alive. Pea Patch Island sits in the Delaware River like a bad decision, damp and overcrowded, and once you picture sick prisoners packed in there, the stories start to make a brutal kind of sense.

During the Civil War, the dead were hauled across the river to Finn’s Point in New Jersey, where thousands of Confederate prisoners still lie in a national cemetery. Meanwhile, visitors and investigators keep describing phantom cannon fire, a figure showing up on thermal imaging, and even doors that open on their own, plus footsteps in empty corridors and shadows sliding along the ramparts.

And then there’s Woodburn, where the governor’s mansion has been getting ghost reports since the 1800s, including a powdered-wig man on the stairs, a red-dressed girl, and a wine-drinking specter, all layered over Underground Railroad history.

Fort Delaware: The Most Haunted Place in Delaware

Pea Patch Island sits in the middle of the Delaware River, and everything about its geography worked against the men imprisoned there. Damp, overcrowded, disease-ridden. The dead were ferried across the river and buried at Finn's Point in New Jersey, where thousands of Confederate prisoners lie in a national cemetery and where forgotten soldiers still get headstones placed generations late.

The fort, now a state park reachable only by ferry, appeared on Ghost Hunters, where investigators reported phantom cannon fire, a figure on thermal imaging, and one team member being physically touched. The Diamond State Ghost Investigators have run paranormal tours there for over 15 years and describe doors opening on their own, footsteps in empty corridors, and shadows moving along the ramparts.

Visitors regularly claim to see soldiers in period uniform watching tour groups pass, then finding the same figures in their photos afterward. The official DNREC account of the fort's hauntings treats the subject with surprising seriousness for a state agency.

Isolated islands used for containing the sick and the condemned tend to accumulate stories, from New York's forbidden quarantine island to Pea Patch. Put enough suffering in one place with no way off, and the place remembers.

Woodburn: The Haunted Governor's Mansion

Delaware's sitting governor lives in a haunted house. Officially. Woodburn, built in the 1790s in Dover, has hosted ghost reports since around 1815, when a guest described meeting a man in a powdered wig and knee britches on the stairs.

The apparition is usually identified as Charles Hillyard III, who built the house. Later residents added a girl in a red dress and a wine-drinking specter to the roster. The house also served as a stop on the Underground Railroad, another layer of history soaked into the walls.

The state's own website documents the hauntings, which makes Woodburn one of the few executive residences in America with government-acknowledged ghosts.

Rockwood Mansion: Gothic Revival, Complete With Pet Cemetery

Rockwood was built between 1851 and 1854 as the retirement estate of merchant banker Joseph Shipley, designed to look like an English country house. It ended up looking like the cover of a Gothic novel instead, right down to the pet cemetery on the grounds.

Staff report a man in a red smoking jacket and the ghost of Shipley's great-niece Mary Bringhurst, who died in the home in 1965 at age 100. The mansion has been featured on Ghost Hunters and got a CBS segment for its hauntings. New Castle County runs tours, and October bookings fill fast.

The Headless Soldier of Cooch's Bridge

Cooch's Bridge, near Newark, was the only Revolutionary War battle fought on Delaware soil and, by tradition, the first battle where the Stars and Stripes flew. The battle left behind the state's oldest ghost story: a headless British soldier, decapitated by a cannonball, who wanders the Old Baltimore Pike on foggy, moonless nights looking for his head.

There's one historical wrinkle. The Americans at Cooch's Bridge didn't have cannons. If the story is true, the man was killed by his own side.

That ferry ride to Pea Patch is the part people can control, but the phantom cannon fire and the “touched” team member are the parts they can’t.</p>

When you add in the prisoners being ferried to Finn’s Point, the hauntings stop sounding random and start sounding like a memory that refuses to stay buried.</p>

So it’s not surprising that Woodburn’s stairway has its own lineup, with Charles Hillyard III in powdered wig and knee britches, plus the red dress and the wine-drinking ghost.</p>

And because Woodburn also served the Underground Railroad, every new report feels less like spooky entertainment and more like another chapter that never got finished.</p>

Small State, Long Memory

Delaware's ghost stories skew older than most states can manage. A 1777 battlefield. A 1790s mansion. An 1812 cannonball. A Civil War prison. Delaware was there for every American catastrophe from the Revolution onward, and at 1,982 square miles, there was nowhere for the aftermath to spread out.

Delaware Today's roundup of the state's hauntings counts a dozen major sites in a state you can drive across in half an hour. Per square mile, the First State might be the most haunted real estate in the country.

Delaware’s haunted places don’t just scare you, they make you feel like you walked into someone else’s unfinished history.
