Schloss Heroldeck graces the northern shores of Millstätter See in Carinthia, surrounded by alpine peaks and commanding panoramic views of the serene lake. Originally constructed as a summer residence for an Austrian noble family, the castle underwent significant renovation during World War I and experienced further transformation under subsequent ownership. Since 1988, Calvary Chapel has managed the property as a spiritual education center and conference venue, adapting its interior to serve as both a small hotel with dormitory accommodations and a separate pension for couples and families. The castle's striking façade and elevated position on Kaiser-Franz-Josef-Straße make it a distinctive landmark in Millstatt, attracting church groups and communities for retreats, courses, and gatherings in this picturesque Alpine setting overlooking one of Austria's most beautiful mountain lakes.
