altonale

The 2025 edition, under the motto "Resonanz", invited encounters, changes of perspective, and new impulses. The Platz der Republik was once again the festival center with a daily stage program; the program was spread decentrally across numerous venues in Altona-Altstadt and Ottensen.

The STAMP festival from July 4 to 6, 2025, transformed Altona's squares into lively stages for performative art in public spaces. The altonale flea market, one of Hamburg's largest second-hand markets, and the art mile with local artists complemented the program. "Pay what you want" remained the admission model.
