Guided tour - The Letters to Drottningskär Citadel

Drottningskär Fortress is considered one of the finest examples of Swedish fortification, featuring innovative fortification techniques developed by the military and architect Erik Dahlbergh. Construction of the coastal fortress began in conjunction with the establishment of the new naval base at Karlskrona in 1680. Since defending the entrance to the naval harbor was of the utmost importance, fortifications were needed on the two islands of Tjurkö and Aspö; thus, Kungsholm Fort and Drottningskär were built on either side of the entrance.

Visit Drottningskär Citadel during fall break and join an exciting guided tour for families with children. Listen to stories about historical figures and join one of them on a hunt for hidden letters. A fun experience where children and adults can discover history together in a playful way.
