This fort has defended the entrance to Karlskrona for more than 300 years. Kungsholms Fort is still operational within the Swedish defences. The remarkable round harbour has become somewhat of a symbol for Karlskrona’s status as a World Heritage site. Exotic plants from all corners of the globe flourish under the protection of the fort’s walls. They have been brought here over many years on vessels returning from distant voyages. A museum on the island depicts the fort’s history. There are regular guided tours to Kungsholms Fort during the summer, visits can also be arranged for groups and individuals at other times.
