The three castles were built on a single ridge but functioned as separate entities with individual keeps and defensive walls.
Wahlenbourg, the central castle, was the first to be constructed around 1006 by Hugo IV of Nordgau.
The site was abandoned after being captured and dismantled by the troops of the city of Mulhouse and the Bishop of Basel in 1466.
The castles were historically used as a strategic lookout point to monitor the entrance to the Fecht valley.
Construction materials were sourced locally from the red sandstone common to the Vosges mountains.
The Three Castles of Eguisheim, known locally as Les Trois Châteaux d'Eguisheim, consist of the ruins of three separate fortifications—Wahlenbourg, Dagsbourg, and Weckmund—situated atop the Schlossberg hill at an elevation of 591 meters. The site overlooks the village of Eguisheim and the surrounding Alsatian vineyard plains. Constructed primarily in the 11th and 12th centuries, the castles were built for the Counts of Eguisheim and the Bishops of Strasbourg. The fortifications were largely destroyed during the 15th-century conflict known as the Sundgau War. Visitors access the ruins via a network of forest trails that link the three distinct castle foundations. The site remains largely unmanicured, preserving the crumbling sandstone masonry of the original residential towers and curtain walls. It is a protected archaeological site integrated into the larger Vosges mountain forest landscape.

Wear sturdy hiking boots as the paths are uneven, rocky, and can be slippery after rainfall.
Bring sufficient water and snacks, as there are no facilities or vendors at the top of the hill.
Use a physical map or GPS trail app, as forest signage can be inconsistent at junction points.
Attempting to drive all the way to the top; there is a dedicated parking area further down the hill, and the final stretch must be completed on foot.
Stay on marked trails to protect the fragile ruins and respect the natural environment; climbing on the unstable masonry is prohibited.
