Ort Castle (Seeschloss Ort) stands uniquely on a small island within Lake Traunsee in Gmunden, accessed via a 123-meter bridge from the mainland. Founded around 1080 by Hartnidus of Ort, the castle passed through ownership by the Wallsee family, emperors Frederick III and Leopold I, before being acquired by Gmunden municipality in 1995. The castle gained international prominence as the filming location for the popular Austrian-German television series "Schlosshotel Orth" (1996-2004). Today, it functions as both a museum and cultural venue hosting concerts, theater performances, and festivals throughout the year, offering visitors a unique lakeside castle experience.
