Gosport sits across the harbour from Portsmouth and shares its naval heritage without the crowds. The town is home to the Royal Navy Submarine Museum, where you can tour HMS Alliance, a World War II-era submarine preserved in remarkable detail. Explosion, the Museum of Naval Firepower, occupies a former armaments depot on the Gosport waterfront.
The Gosport ferry across to Portsmouth is one of the best short boat rides in England — a few minutes across the harbour mouth with views of the Historic Dockyard, HMS Victory, and the Spinnaker Tower. Fort Blockhouse and the Haslar sea wall make for a good waterfront walk. The Royal Hospital Haslar, an enormous Georgian naval hospital that closed only in 2009, is one of the most impressive institutional buildings in Hampshire.
