The castle covers an area of approximately 2,000 square meters, making it the largest in the Alsace region.
It was built during the political struggle between the Habsburgs and the Bishopric of Basel.
The masonry incorporates local granite and pink sandstone, reflecting the geology of the Vosges mountains.
During the Thirty Years' War, the fortress was heavily damaged and subsequently dismantled to prevent it from being used as a base.
Excavations revealed that the site was occupied as far back as the Bronze Age, long before the medieval structure was erected.
Château du Hohlandsbourg is a 13th-century fortress situated on a volcanic spur at an elevation of 620 meters above the Alsace plain. Constructed in 1279 by Siegfried von Gundolsheim under the authority of Rudolf of Habsburg, it served as a strategic military stronghold to monitor the surrounding region. The site features extensive curtain walls, a rectangular keep, and an inner courtyard that has been stabilized and restored for public access. It remains one of the largest fortified complexes in the Haut-Rhin department. Archaeological excavations have unearthed medieval artifacts and structural foundations now presented within the on-site exhibition areas. The castle provides panoramic views stretching across the Vosges mountains, the Black Forest, and the plain of Alsace. It operates as a heritage site hosting temporary historical exhibitions and seasonal cultural events. The site is characterized by its expansive rampart walks that allow visitors to traverse the perimeter of the medieval defensive works.
The elevated walkway along the north ramparts, providing a wide-angle view of the Alsace plain and the surrounding forest canopy.
Wear sturdy, closed-toe walking shoes as the site features uneven cobblestone paths and gravel surfaces.
Bring windproof clothing, as the exposed elevated location experiences significant drafts even on sunny days.
Check the official schedule before departure, as the site periodically hosts private events or reenactments that may affect access to certain courtyards.
Do not attempt to climb or sit on the remaining perimeter walls, which are original ruins and can be unstable.
Closed from mid-November through March; typically open daily during the primary season with occasional closures for private events.
Maintain respectful distance from loose stone masonry; stay within marked visitor pathways on the ramparts.
