Hammershus Castle Ruins
Northern Europe's largest castle ruin crowning a clifftop fortress with Baltic views, free and open 24/7.
Northern Europe's largest castle ruin crowns a dramatic clifftop on Bornholm's northwestern coast, commanding sweeping views of the Baltic Sea. Built in the late 13th century by Archbishop Jens Grand, this medieval fortress served as the island's administrative stronghold for over 450 years before its abandonment in 1743. Today, the restored ruins stand as Bornholm's most visited landmark, accessible 24/7 and entirely free to explore, complemented by a modern visitor center with exhibitions, café, and panoramic viewing terraces.

Local tips
- Visit early morning or late evening for solitude and exceptional photography, as the castle is accessible 24/7 while most visitors arrive during daytime hours.
- Combine your visit with the Stonecutters' Path, a marked 5.5-kilometer trail nearby that reveals Bornholm's quarrying heritage through dramatic rock formations and crevasse valleys.
- Wear sturdy footwear and layered clothing; the clifftop location experiences variable weather, and pathways can be uneven or slippery in wet conditions.
- Allocate at least 2–3 hours to explore the ruins, visit the exhibition at the visitor center, and enjoy the panoramic terrace views without rushing.
- Check visitor center opening hours before visiting in winter months, as the center operates weekends only from November through Easter, though the castle ruins remain accessible.

A Medieval Fortress Shaped by Power and Conflict
Hammershus Castle Ruins represent one of the most significant medieval fortifications in Northern Europe, with roots extending back to the late 13th century. Recent archaeological research and excavations from 2015 suggest the fortress was completed around 1300, built by Archbishop Jens Grand of Lund to consolidate ecclesiastical control over Bornholm Island. The castle's strategic position on a steep rocky prominence at the island's northern tip made it an ideal defensive stronghold, overlooking the Baltic Sea and controlling vital maritime routes between Denmark, Sweden, and Poland. The fortress emerged during a turbulent period of Danish history marked by power struggles between the Crown and the Catholic Church. When the archbishop's forces destroyed the rival fortress of Lilleborg in the island's center in 1259, Hammershus became the undisputed seat of authority on Bornholm. For the next five centuries, the castle served as the headquarters of successive rulers, undergoing multiple expansions and renovations that reflected changing military technologies and political circumstances.Centuries of Occupation and Transformation
Hammershus endured a complex history of foreign occupation and shifting allegiances. From 1525 to 1575, the fortress fell under the control of the City of Lübeck, the powerful Hanseatic League merchant federation. Swedish forces occupied the castle twice—briefly from 1643 to 1645 and again in 1658—before local resistance movements restored Danish sovereignty. The castle even served as a prison; notably, in 1660–1661, King Christian IV's daughter Leonora Christina and her husband Corfitz Ulfeldt were imprisoned within its walls for treason, though their dramatic escape attempt down the fortress walls and cliffs ultimately failed. By the late 17th century, Hammershus's military importance had diminished as Denmark's eastern defenses shifted to the fortress on nearby Christiansø and fortifications at Rønne. The castle was finally abandoned as a stronghold in 1743, and for nearly 80 years, local residents freely quarried its bricks for building materials. This practice ended in 1822 when the Danish State granted Hammershus protected status as a national monument, recognizing its historical and cultural significance during the era of Danish nationalistic revival.The Ruins Today: Scale and Preservation
Today, Hammershus stands as Northern Europe's largest castle ruin, its restored stone walls and towers rising majestically above the surrounding landscape. A distinctive medieval stone bridge—the only surviving example of its kind in Denmark—leads across a dramatic gorge to the fortress entrance. The ruins themselves remain largely inaccessible for climbing, as preservation measures restrict visitors to designated pathways and viewing areas, allowing safe exploration while protecting the ancient stonework. The 2018 opening of the Hammershus Visitor Center transformed the visitor experience without compromising the site's historical integrity. Positioned approximately 200 meters east of the castle and separated by a natural gorge, the modern facility blends seamlessly into the landscape through thoughtful architectural design. Large panoramic windows frame spectacular views of the fortress and Baltic Sea, creating a visual dialogue between contemporary architecture and medieval ruins. Inside, comprehensive exhibitions chronicle the castle's rich history, from its construction through its role as an administrative center, fortress, and prison.A Living Landscape of History and Nature
The setting itself contributes profoundly to Hammershus's appeal. Perched on steep cliffs overlooking the Baltic, the ruins command one of Bornholm's most dramatic natural landscapes. The surrounding area reveals traces of the island's industrial past through the Stonecutters' Path, a 5.5-kilometer marked trail that winds through quarries and crevasse valleys, following routes once used by granite workers transporting stone from Sandvig to Hammerhavn. Nearby attractions including Hammeren Fyr lighthouse (built 1872) and opportunities for rock climbing, zip-lining, and stand-up paddleboarding make the region a hub for both cultural and outdoor experiences. The castle's accessibility—open 24/7 and entirely free—ensures that visitors can experience its majesty at any hour, whether bathed in summer sunlight, softened by autumn mist, or dusted with winter snow. The visitor center's seasonal operations (extended summer hours, weekend-only winter access) accommodate varying travel patterns while the ruins themselves remain perpetually open to those seeking solitude or dramatic photography at dawn or dusk.Iconic landmarks you can’t miss
