'Das Ursakirche' is a migrational and rewilding facility designed for bears. After being transported from the Tiergarten Schönbrunn, Vienna, it allows the bears to learn to forage, fight and court through an artificial landscape created in Sigmund Freud Park. The bears are migrated periodically from the Ursakirche to the Alps where further rewilding can be conducted. They traverse the surface of the building as its human researchers and pagan bear worshippers are kept inside, reversing the spatial relationships of zoos. With these features in place, the Ursakirche aims to create an atmosphere in which the sentimental ritual of the church facing the scheme is replaced by the raw and the feral, allowing humanity to fear nature once more.
