In the page's words:

Founded in 1998, the theater focuses on theater performances, but occasionally also offers cabaret and music. The theater is located in the heart of Frankfurt's Nordend district, in a former dance hall that was added to a massive castle-like building from the 15th century around 140 years ago. The most unusual thing about the theater is the high number of in-house productions. They now make up almost 80 percent of the program, and the trend is rising. And some of them have already been performed more than 750 times! Come and take a look.
