Another work by Christoph Brech is encountered at the entrance to the pavilion: the video piece Zeichen (Sign). A bell tolls—its sound extending outward, cutting through the air. It functions as a signal: an alarm, a marker of passing time, a call to recognize the critical moment when decisive action becomes essential. The sound draws visitors into the pavilion—at once a warning and an invitation. Like the whirlwinds on the roof, Zeichenunderscores the urgency of the present. Through its symbolic force, metaphorical richness, and social resonance, the work highlights the pressing need for awareness and response.
