Bavarian State Opera Rehearsal Building
Pedestrians walk past the ''Buehnenfenster'' installation by Olafur Eliasson on the Bavarian State Opera rehearsal building facade at Marstallplatz in Munich, Bavaria, Germany, on March 21, 2026. The glass changes color depending on the viewing angle and daylight due to nanotechnology at the atomic level, reflecting life on the square and connecting interior and exterior spaces as a theatrical stage for the city.
