History & Significance

First established in 1889 as Winthrop Military Reservation and formally named Fort Banks on July 22, 1899, this coastal fort defended Boston Harbor during the Spanish-American War and beyond. The fort's two eastern and western mortar pits, designated Battery Sanford Kellogg and Battery Benjamin Lincoln, were the first Endicott gun batteries completed in Boston and the first 12-inch coast defense mortar batteries anywhere in the U.S., with construction completed in 1896; the mortars were taken out of service in 1942.

The four mortar pits were arranged in an "Abbot Quad" design containing 16 mortars that, if fired in salvo with parallel aim, would bracket an attacking ship in fire; since each shell could weigh over half a ton, a 16-mortar salvo delivered over 8 tons of steel and explosives designed as a deterrent to ships approaching Boston Harbor's northern channels. During World War II, Fort Banks served as the anti-aircraft defense command post, meteorological station, and secure switchboard bunker for Harbor Command, and became headquarters for the Army's 9th Coast Artillery Regiment, which garrisoned much of Boston's harbor defenses.

After declaration as surplus in 1947, land was purchased by the Town of Winthrop and private developers for municipal facilities and apartments. The fort was added to the National Register of Historic Places in 2007.
