Climate activist Greta Thunberg seems to want to share her concerns with the statue of Our Lady on the facade of the former chapel of the Capuchin monastery. But the chapel has long been converted into a joinery workshop and the owner took the initiative to show his sympathy for the activist in 2019 with this fresco. A similar fresco had also appeared in Brussels a few months earlier. The artist: Philippe Baro (Switzerland) made the work in a few hours with the help of an overhead projector.
