The Jyrkkä summer theatre is located at the Kainasto Youth Club in Ylistaro. The theatre can accommodate approximately 400 spectators. In 2016, a new cover was installed, the benches were replaced with individual seats, and the terrace was made steeper in order to improve visibility. The summer theatre performs productions by Kyrönmaa College and the local Ylistaro theatre group. Audience members can use the facilities at the youth club.
