The lighthouse consists of 44 stairs that lead up to the Watchroom, a circular room with three portholes. Many strange happenings have occurred in this room, one being a female lighthouse enthusiast, who heard voices, only to find she was alone inside. Another witness to this paranormal activity heard a man ask, What are you doing? only to discover there wasn't a person in sight. Many believe Joshua Card, the former lighthouse keeper, who preferred to go by the name Captain, haunts this place. Fort Constitution mainly served the country as a lookout and supply storage unit through many wars since the 1630's. The fort was one of Paul Revere's first stops on his way to warning colonists about the impending Revolutionary War. The fort consists of a lookout area, a powder magazine, a sentry room where prisoners were held, and sally ports on each side that served as entryways. On July 4, 1809, disaster erupted at Fort Constitution. Gunpowder that was reserved for a fireworks display accidentally exploded killing 14 people, most of whom were children. Some believe it is the residual ghosts of the 1809 explosion that haunt the structure today. Members of the Coast Guard are afraid to go into Fort Constitution at night because of the general noises they hear and its eerie nature.
