In the middle of Vienna's (and Europe's) largest inner city park, this club has become a staple in the dance music scene. As the name suggests, the location used to be a fitness club and sauna, and although the pool remains the patrons are not there for their health. The vibe is more laid back than most clubs in the Inner City, with an outdoor pool area and multiple floors inside. It also hosts events during the day, as well as art exhibitions. When it comes to decor, the self-dubbed "social life and art space" takes the new vintage approach. Many complain about the inconsistent door policy but, all in all, the place is a big hit, especially for the art-and-fashion crowd. Check the Sauna's website for acts and club nights.
