Pandemic-related restrictions for public traffic: Due to the lockdown regulation of the state of NRW, our office in Cologne-Ehrenfeld is closed.
We are still available by e-mail and telephone. Due to increased work in the home office, there may be a longer response time in individual cases. Thank you for your understanding.
We are open from Monday to Friday from 9:00 a.m. to 5:00 p.m (please note our remark on the left). Our showcase exhibition “Facets” can be visited free of charge during this time but only with registration in advance . At the entrance you will receive a short introduction and a reader (only available in German) for accessing the exhibition independently.
