The Elsa Plainacher Collective – named after a woman who was publicly burned as a “witch” in Vienna (16th century) – is staging a participatory action in Seestadt. “Karlsplatz clay”, which was excavated in 1970 during the construction of the Vienna underground and provided to the ceramics studio, is used to make street signs with the names of female protagonists on Wangari Maathai Square. As a feminist critique of the male-dominated municipal authorites, the signs are distributed around the city.
