The Château du Girsberg is one of three castles (with the Château de Saint-Ulrich and the Haut-Ribeaupierre) which overlook the municipality of Ribeauvillé.
The Lords of Ribeaupierre built the castle, then named Stein (La Roche), in the 13th century. They rebuilt it after a fire caused by lightning in 1288. In 1304, they gave it to their vassals, the knights of Guirsberg, from whom the castle took its name. The Guirsbergs kept it until they died out in the 15th century. It was abandoned in the 17th century.
The remains currently visible contains 13th century pentagonal keep, inner court and corps de logis from the 14th-15th centuries.
