If you like your Swedes in uniform, you’ll appreciate Karlskrona. Marine cadets pepper the streets of what has always been an A-league naval base. In 1998 the entire town was added to the Unesco World Heritage list for its impressive collection of 17th- and 18th-century naval architecture.
It was the failed Danish invasion of Skåne in 1679 that sparked Karlskrona’s conception, when King Karl XI decided that a southern naval base was needed for better control over the Baltic Sea. Almost immediately, it became Sweden’s third-biggest city. Much of the town is still a military base, so to see certain sights you’ll need to book a tour at the tourist office and have ID at the ready.
