The Château du Landsberg is a castle in the commune of Heiligenstein in the Bas-Rhin département in Alsace, France.
The castle includes a Zwinger with two sets of defensive walls.
It has been listed since 1965 as a monument historique by the French Ministry of Culture.
[1] The central part of the castle was built in the late 12th century, and the newer outer castle added onto at the start of the 13th century[2] by Conrad de Landsberg to provide defence for the abbeys of Mont Sainte-Odile, Niedermunster, Truttenhausen and Andlau.
