Contemporary artists of all ages from the genres of painting, graphic art and photography are presented on the upper floor of the C-Keller am Markt 21. Project exhibitions such as room installations, video art and sculptures are also shown on a rotating basis. The exhibitions have a socio-cultural and non-commercial character. The house also has a bar: concerts with young musicians from the national and international scene take place regularly. The repertoire ranges from jazz to rock, pop and alternative.
