iFounded in 1961 by collector J. Welles Henderson and housed on Penn's Landing since 1995, the Independence Seaport Museum tells the story of the Delaware River and the city that grew along it. Galleries cover the founding of the US Navy in Philadelphia, the China trade, immigration, shipbuilding and river ecology, alongside a collection of ship models, rare books and maritime art. Moored outside are two National Historic Landmark vessels: the 1892 cruiser USS Olympia, Dewey's flagship at Manila Bay and the oldest steel warship still afloat, and the WWII submarine USS Becuna. A working boat shop and a hands-on river gallery round out the visit.

Around 150 rarely seen objects trace how the young United States, cut off from British trade after the Revolution, turned east to China and built itself into a global economic power.

Aboard the cruiser Olympia, a rarely told account of the Philippine-American War and the symbols born of it, made with the Filipino Executive Council of Greater Philadelphia.

Nearly 50 rarely shown ship models, from US Navy vessels and pond yachts to the toy craft sailed across the floors of grand Victorian houses in the 19th century.

Opening March 2027: almost 400 years of Black Philadelphians and the Delaware River, from the portal of enslavement to a route for freedom seekers, a source of labour and a place of celebration.

Over 100 treasures from the collection, most never previously displayed, introducing Philadelphia's Revolutionary naval history and the shipyards of the Delaware River.

Launched in 1944 and berthed at Penn's Landing since 1976, the USS Becuna is toured with a guide: torpedo rooms, cramped bunks and the machinery that kept 80 men alive underwater.

The US Navy was founded in Philadelphia. This gallery covers the fight against the Barbary pirates and lets you climb aboard Diligence, a replica 1797 schooner built in the museum's own boat shop.

Hands-on gallery about the Delaware River, which supplies drinking water to 15 million people, with water play, a larger-than-life video game and conservation exhibits for families.

Commissioned in 1895 and the oldest steel warship still afloat, Dewey's Manila Bay flagship is open deck by deck, from officers' quarters and galley to the sick bay and engine rooms.
