The castle grounds are located exactly on the border between the French commune of Leymen and the Swiss municipality of Flüh.
During the 16th century, the castle was used to house a private collection of bears, a tradition that was historically common among nobility of that era.
The site features a significant dry moat carved directly into the limestone rock, which served as a primary defensive barrier.
Archaeological evidence suggests the site was inhabited long before the medieval structure, dating back to Roman and even prehistoric settlements.
The castle changed ownership frequently, shifting between the Habsburgs, the Bishop of Basel, and the French crown.
Château du Landskron is a 13th-century hilltop fortification located on the border of France and Switzerland. Built by the Lords of Landskron, the castle sits at an altitude of 565 meters on a rocky spur overlooking the Leimental valley. Its strategic position necessitated frequent defensive modifications, resulting in a complex of curtains, round towers, and a deep dry moat. Historically, it served as an important defensive point for the Prince-Bishopric of Basel. The site was extensively damaged during the Thirty Years' War, leading to its eventual decline into a ruinous state. Today, it is managed by the Association pour la Sauvegarde du Château du Landskron, which oversees ongoing structural preservation. Visitors can access the interior courtyards and ramparts, which provide extensive views of the surrounding Jura mountains and the Basel region.
