Description: The Grand Battery. Known also as the Association Battery, this was Pennsylvania's largest early fortification. Originally built in 1748, shortly after formation of a volunteer military force called the Association, it mounted 27 guns; within a few years it held some 50 guns. Later the first Philadelphia Navy Yard was here, 1800-1875. A short distance to the north, the smaller Society Hill Battery was built in April 1748; it mounted 13 guns.
