The CADORO art gallery is located in Mainz-Hechtsheim and, as a meeting place, attracts not only many art lovers from the region. CADORO was initiated by Dorothea van der Koelen and her Van der Koelen Foundation for Art and Science, which she established in 2003. To this day, it combines a research center with exhibition spaces for the scientific study of contemporary art.

Opening hours: Wednesdays from 10 a.m. to 4 p.m. and Saturdays from 11 a.m. to 4 p.m.
