Located on an island in the entrance to Karlshamn guest 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 an exciting, easy-to-reach destination for visitors of all ages, guided tours and art exhibitions, for example. In recent years Kastellet has provided the scenery and venue for the extremely popular summer theatre organised by an amateur theatre company.
During the summer season you can visit the island and the boat leaves from the "Skärgårdsterminal" (next to the guest harbour in town centre).
Tickets are available at the boat.
