Château du Haut-Barr is a medieval fortress perched 470 metres above Saverne in Alsace, earning the nickname "the Eye of Alsace" for its strategic position overlooking the Zorn valley and the Plain of Alsace. Built in 1100 by the Bishop of Strasbourg, the castle stands atop three sandstone rocks and exemplifies medieval defensive architecture, with later modifications made in the 16th century to accommodate firearms. Though partially dismantled during the Thirty Years' War, the castle now welcomes visitors freely and features a popular café-restaurant within its walls, making it an accessible destination for those seeking panoramic views and historic ambiance just a short distance from the town centre.
