Origin and history

The Castle of the Landskron, built before 1297 on a strategic hill of the Sundgau in Leimen (High Rhine), controlled the elbow of the Rhine and the road to Basel. From the time of its construction, it was the object of rivalries between local lords before it became a Habsburg domination, thus integrating earlier Austria. Its military role and border position made it a major territorial issue until the 17th century.

In 1462 the castle was entrusted in bailliage to Reichenstein lords, who enlarged it in 1516 to adapt it to artillery. After Alsace joined France in 1648 (Treaty of Westphalia), Vauban transformed it into a modern fortress between 1665 and 1684, adding strongholds and dread. The site also became a state prison under Louis XIV, welcoming prisoners by letter of stamp until the Revolution.

Destroyed in 1813 by Austrian and Bavarian troops during the French campaign, only his dungeon was spared thanks to the intervention of a local parish priest. Abandoned, the castle fell into ruins in the 19th century. In the 20th century, it briefly housed a colony of monkeys (1970s), before being bought in 1984 by the Franco-Swiss association Pro-Landskron, which undertook partial restorations from 1996.

Today, the accessible ruins of the Landskron bear witness to its military past and offer an exceptional view of the Alsatian plain and neighbouring Switzerland. Ranked a historic monument since 1923, the site combines medieval heritage and Franco-European history, symbolizing conflicts and exchanges between France, Austria and the Swiss cantons.

Architecturally, the castle is distinguished by its rectangular dungeon, typical of the Alsatian fortresses, and its defensive systems such as the hers protecting the entrance. The plans of 1764 reveal a structure adapted to modern wars, combining medieval heritage and innovations of Vauban.
