Galerie Mueller was established in 2018 by owner and director Dominik Müller. It is located in a rear building at Rebgasse 46 in Kleinbasel. It organises up to four art historically founded exhibitions annually, practices dealing in art and offers various services in the art area. The conceptual orientation is art of late 19th and 20th century. An important criteria in the selection of the works and artists shown is their close or loose relation to the location of the gallery: the city of Basel.
