The Hardau park lies in the Hardau district well to the west of Langstrasse, an area with cheaper apartment blocks and a large immigrant population. The highlight of this multifunctional park is the huge white y-shaped sculpture by Sisley Xhafa. Does it scream 'why'? Is it a catapult? Yes, but it's also a giant toy, a swing open for use by the parks visitors, which glows in different colours when used. Xhafa, a Kosovar living in New York, picks up on serious subjects: resistance, conflict, despair, subjects the immigrant knows particularly well. And who isn't an immigrant nowadays?
