The red main curtain is designed as a classic Wagner curtain. The special feature of a Wagner curtain is that the curtain is about twice as high as the part visible to the spectators. Crucial for Wagner curtains is the exact course of the rope on the curtain, which has to be adapted to the structural conditions of the stage and the stage portal.
Only the combination of overheight and rope course lead to the classic image of an open Wagner curtain.

In addition to the classical Wagner opening, the Wagner curtain in the Graz Opera can also be opened in the middle as a Greek curtain.
