Hammershus Castle Ruins
Northern Europe's largest medieval fortress ruin
Towering 13th-century granite ramparts perched on sea cliffs 74 metres above the crashing Baltic surf.

In 60 seconds
Bornholm is Denmark's Baltic island outlier: rocky granite cliffs, whitewashed fortified round churches, and historic smokehouses with conical chimneys. From the dramatic promontory ruins of Hammershus to the hourglass powder sands of Dueodde, Bornholm has also become a culinary powerhouse crowned by Kadeau's wild island foraging.
