Fort Decker is the oldest house in Port Jervis and was built in 1793 from the remains of a stone fort built during the French and Indian War. It later housed engineers working on the Delaware and Hudson Canal construction, including Port Jervis' namesake, John Bloomfield Jervis. In 1958, the Minisink Valley Historical Society bought the house and converted it into a museum.
