Taggenbrunner Festspiele takes place at Burg Taggenbrunn, a restored medieval castle-ruin located on a hilltop near Sankt Georgen am Längsee in Carinthia, Austria. Originally constructed in the first third of the 12th century by Tagenus of Pongau on commission of the Archbishop of Salzburg, the castle was built atop the remains of a Celtic-Roman ringwall settlement dating to the 6th century BC. After centuries of historical significance, the castle underwent extensive restoration and now serves as a vibrant cultural venue. The restored castle hall hosts the Taggenbrunner Festspiele, an annual festival established in 2019 that emphasises classical music, jazz, and opera productions of high calibre. Beyond performances, the site accommodates a restaurant and hosts art exhibitions, making it a multifaceted cultural destination that honours its medieval heritage while serving contemporary artistic audiences.
