'Navy Yard', 1874. Ships on the Delaware River at Philadelphia, Pennsylvania, USA. The Philadelphia Naval Shipyard was the first shipyard to be built for the US Navy, and was in use from 1801 until its closure in 1995. 'To the south [the artist's] roving eye will first be caught by the old Navy- Yard, with its ark-like ship-houses, its tiers of masts and docks, and the green oases of its officers' quarters'.
