Kastelholm Castle, Medieval castle and museum in Sund, Finland.
The gray stone fortress stands on a former islet with two sides still bordered by water, featuring multiple towers and defensive walls.
Built in the 1380s, the castle served as a military and administrative center for the Swedish Empire, controlling maritime routes in the Baltic Sea.
The castle maintains exhibitions displaying medieval weapons, furniture, and documents that showcase the daily operations of a Nordic fortress.
Kastelholm Castle opens from May through September, with guided tours available in multiple languages explaining the medieval architecture and defense systems.
The castle housed King Erik XIV of Sweden and his wife Karin Månsdotter as prisoners in 1571 during a complex succession dispute.
