Traunsee Castle, also known as Württemberg Castle, is a stunning neo-Renaissance villa constructed in the late 19th century on the shore of Lake Traun in Upper Austria's Salzkammergut. Duke Philipp of Württemberg commissioned the residence as a wedding gift to his wife Archduchess Maria Theresa, initially named Villa Maria Theresa as a peaceful retreat from Vienna's heat and dust. Distinguished architects shaped the castle: Heinrich Adam designed the main structure while Heinrich von Ferstel, architect of Vienna's Votive Church, created the elegant chapel. Though now owned by the Austrian state and functioning as a boarding school inaccessible to the public, the castle's imposing neo-Renaissance façade remains an iconic sight from the lake shore, perfectly reflecting the grandeur and refinement of Upper Austrian heritage.
