To reexamine the seemingly self-evident act of breathing, this performative walk leads to a place where breath once became a problem: Ziegelklinge, a housing settlement built in 1929, colloquially known as “Hustenburg” (Cough Castle). Originally constructed to house tuberculosis patients, the site still negotiates the relationship between architecture, environment, and breath.The walk through this semi-private terrain invites participants to experience the spatial aspects of breathing: an open-air terrace overlooking highways, mature trees, stretched clotheslines, and a hillside crisscrossed by terraces and stone stairways.
