The open-air theatre seating more than 1200 spectators at this sprawling 18th-century monastery, remodelled by local architect Jože Plečnik in the 1950s, hosts the events of the summer Ljubljana Festival. The smaller Knights Hall (Viteška Dvorana) is the venue for chamber concerts.
The venue's location, French Revolution Square, served for centuries as the headquarters of the Teutonic Knights of the Cross (Križniki). They built a commandery here in the early 13th century, which was transformed into the monastery complex in 1714.
