Fortress island located in the entrance of Karlshamn's harbour. The entire island is in fact a fortress dating back to the 17th century when feuds with the Danish were common. Today Kastellet is a beautiful, exciting and easy-to-reach destination for visitors of all ages. For many years Kastellet has provided the scenery and venue for a popular local theatre perfomance during summer time. In the summer season you can visit the island by boat from the inner harbour in Karlshamn.
