And the 1840s vintage fort was built to protect the harbor, but obsolete by the time it was finished. It was used for a century for training and patrol and, during the Civil War, as a prison. Guided tours of historic Fort Warren are offered.
Fort Warren is a historic fort on the 28-acre (110,000 m2) Georges Island at the entrance to Boston Harbor. The fort is named for Revolutionary War hero Dr. Joseph Warren, who sent Paul Revere on his famous ride, and was later killed at the Battle of Bunker Hill. The name was transferred in 1833 from the first Fort Warren – built in 1808 – which was renamed Fort Winthrop.
