The Ravensbruck monument, in a quiet corner of the Museumpleun, is a memorial to the thousands of women who were sent to the Ravensbruck concentration camp in Germany during WWII. It's a curious steel structure. The central column emits light interspersed by a dull beat and the text reads "for women who to the utmost kept saying no to fascism". There is an annual memorial ceremony, attended by a dwindling number of survivors.
