Light gray, square concrete slabs, as we know them from front gardens, cover the venerable herringbone parquet floor of the ground floor of the Kunsthalle. For Klára Hosnedlová (*1990), according to the exhibition text, the flooring has a different connotation: In the former Eastern Bloc, where she grew up, they were a constant present in public spaces. Several slabs are missing at various points, exposing the substrate of gravel and earth. Small puddles of water have formed in the porous ground material; a butterfly, as if frozen in time, sits in one spot. The uncertainty about whether visitors are allowed to enter the installation on the floor, which is not listed as a work, is quickly dispelled. This sets it apart from Carl Andre's 10x10 Altstadt Square (1967) at the neighboring Kunstmuseum Basel. Surrounded by Minimal Art sculptures by Jasper Johns, Sol LeWitt, and Charlotte Posenenske, Andres strictly geometrically arranged steel plates in the white cube appear to belong to a sphere that differs from that of the viewers, despite their unpretentious materiality and many visitors do not dare step onto the flat sculpture. Klára Hosnedlová 's floor situation seems less like a foreign body intended to encourage visitors to participate in a specific way. Rather, it transforms the old building architecture of the exhibition spaces so that it becomes part of her immersive installation itself.
