The castle's keep is uniquely shaped as a pentagon, a design intended to deflect incoming stones from siege engines.
Construction began in the 11th century, making it one of the oldest fortifications in the Alsace region.
The site was held by the Counts of Eguisheim before being transferred to the control of the Strasbourg Bishops.
It is situated on a granite rocky spur, which provided a natural defensive advantage.
The masonry includes evidence of 'bossage,' a technique where stones are left rough-hewn on the exterior face for both aesthetic and structural reinforcement.
Château de Bernstein is a mid-11th-century castle ruin located in the Vosges Mountains at an elevation of 562 meters. It is known for its distinct pentagonal keep, which served as a defensive structure against projectiles. The site remains under the active management and conservation efforts of the Amis du Château de Bernstein association. It features partially preserved curtain walls and offers expansive views of the Alsace plain. The castle was historically linked to the Bishops of Strasbourg and played a strategic role in local medieval territorial conflicts. It was partially destroyed during the 17th century but retains its original Romanesque architectural features. Visitors reach the ruins via a forested hiking trail from the town of Dambach-la-Ville.
