The Château du Petit-Geroldseck is a ruined castle situated in the commune of Haegen in the département of Bas-Rhin in Alsace, France.
It has been listed since 1898 as a monument historique by the French Ministry of Culture.
[1] The destiny of the castle was linked to that of the Château du Grand-Geroldseck, 500 metres (550 yd) north of Petit-Geroldseck.
The ruins themselves are of limited interest, but they provide a view of the hills of Alsace.
The lower court, the keep and remnant of the corps de logis are still visible.
