The Château de Wittschlœssel is a ruined castle situated in the commune of Dambach, in the French département of Bas-Rhin.
[1] The location, a place called Wittschlœssel, means small lock in German.
Built in the 13th century with the name "Schmalenstein", the castle is more of a guard tower, dominating the valley of Obersteinbach.
It became a small fort, completing the security of the nearby Château de Schœneck.
On a rocky crest (altitude 440 m), nothing remains of the castle apart from ruined sandstone walls.
