Château de Hagueneck, Medieval castle in Wettolsheim, France.

Château de Hagueneck is a ruined castle on a granite outcrop at about 440 metres above sea level, west of Wettolsheim. Its rectangular core consists of a square keep seven metres on each side, almost entirely solid, and a residential building within a quadrangular wall. The walls are granite with yellow Rouffach sandstone for window surrounds, and the corners show cushion-shaped bossed stones.

Built around 1230, the castle belonged to Burckhard de Hagueneck, a vassal of the Bishop of Strasbourg who administered lands from this stronghold. Ownership changed hands among regional families over the centuries as political alliances and inheritance reshaped control of the territory.

The structure demonstrates the preferences of medieval Alsatian lords who prioritized residential spaces and status symbols over pure military fortification. The layout shows how the family organized daily life, entertaining guests and managing their territory from this elevated position.

Access to the castle ruins follows a marked hiking path with red diamond blazes starting from a parking area near Wettolsheim. The walk involves moderate climbing, so sturdy footwear and time to explore the scattered remains across the site are recommended.

The castle is the start and end point of the Herzog Path (sentier Herzog), a 2.8 km forest trail laid out by the Herzog family. The site also holds the remains of a semicircular flanking tower on the southeast side, probably built to guard the castle approach.
