The first theatre in Klagenfurt was installed between 1605 and 1620 as Ballhaus for the aristocracy. Italian troupes appeared, on their way from Venice to Vienna. At the end of the 18th century, the theatre was occasionally opened also for intellectuals, and military and civil officials. In 1811, the wooden structure was rebuilt in stone, called now Altes Theater (Old Theatre). •
When it deteriorated, a new house was designed by the Viennese architecture office Fellner & Helmer. Building began in 1908 and was completed in 1910. The house was opened on the occasion of the 60th jubilee of Franz Joseph I of Austria and therefore named "Kaiser Franz Joseph I. Jubiläumstheater".
