In 2019 I started working on my art installation 'Waldlabyrinth' from 2003. And like that the monument got another signification. I covered the tree trunks with bitumen and made it so clear how human actions impair nature and sometimes suffocate. It is a rare example of the change in art objects in public spaces. A necessary change to do justice to the changing living conditions of humans. The tree trunks are a symbol of our time.
