Karlskrona. In the middle of the archipelago.
Drop anchor in Karlskrona, the city that was founded in 1680, when Karl XI decided to build Sweden's new naval base here. More than 340 years later, the naval base remains and the well-preserved architecture and city plan impressed UNESCO, and gave the city World Heritage status in 1998. Wherever you go, you can see evidence of this; magnificent churches, grand squares, parade streets and fortifications that attract visitors from all over the world.
And all this on a number of islands, in the middle of the archipelago. An archipelago that UNESCO has designated as one of seven biosphere reserves in Sweden. Nowhere else in the world can you paddle around a UNESCO Biosphere Reserve while enjoying the amazing fortifications and buildings of a World Heritage city.
