[1] The largest theater in Upper Austria (OÖ), it consists of three venues: the Musiktheater am Volksgarten, the Schauspielhaus (formerly Großes Haus) and the Kammerspiele on the Promenade in Linz.

In 1751, the Linz master builder Johann Matthias Krinner made a proposal to the estates to erect their own theater building.

From 1752 to 1786, the location at Promenade 39, a converted warehouse, was only a temporary solution for the frequent times when the municipal water theater on the Donaulände in the area of today's Zollamtstraße was unusable due to flooding.

[citation needed] In summer 2008, the listed façade of the Linz Landestheater was given back the shade of yellow that the building had in 1803 according to the analysis of the monument conservationists.

During this time, the Great Hall of the old building of the Anton Bruckner Private University was used as an alternative venue for the drama production Franz Grillparzer's Das goldene Vlies.

In the 2017/18 season, the former orchestra rehearsal hall on the Promenade was opened as a new studio stage for drama and young theater, replacing the previous venue.
