Castle Ruins and Fortress Sites
For thousands of years, Bornholm has been an important hub in the Baltic Sea, and the island holds traces of defensive structures dating back to prehistoric times. Later Iron Age sites and medieval castles continue this tradition with more prominent constructions. Across the island you will find ruins, earthworks and strategic elevated locations that testify to conflicts, centres of power and the need for protection through changing periods. Together they provide a fascinating insight into Bornholm’s long and strategically important history.
