A few steps from the central shopping action is Maritiman (maritiman.se), the world’s largest floating ship museum. It’s made up of 20 historical craft, including fishing boats, a light vessel and a firefighter, all linked by walkways.
Inside the labyrinthine 121m-long destroyer Småland, in service from 1952 to 1979, hunched figures listen to crackling radio messages, and the bunks look just slept-in – you half expect to meet uniformed sailors in the dim, twisting passages. Shimmy down into the 69m-long submarine Nordkaparen for a glimpse into underwater warfare. The museum is not open every day; check the website before visiting.
