Brief history of the fort
Construction of Fort Warren on Georges Island began in 1833. It was built of granite from nearby Quincy and from Cape Ann. It was already obsolete before it was completed because of several major technological military changes such as high-powered cannons and ironclad ships. Construction was conducted in several stages until the Civil War started.
The Civil War
World War I
World War II
New recruits were again trained at Fort Warren during World War II. The fort also continued as an important mine control center. Mines were maintained at the brick mine storage building which is used today as the fort's visitor center.
Here is a short Fort Warren movie taken in the spring of 1958 during a Boston fireboat shore inspection. Some of the old buildings were still standing. The grass on the parade ground was over 2 feet tall and had not been mowed since the war ended—and the troops left. Only a lone government caretaker lived on the island at the time this film clip was made.
In 1958 the federal government turned Fort Warren over to the Commonwealth of Massachusetts, and in 1961 the fort was opened to the public. In 1970 Fort Warren was designated as a National Historic Landmark.
