Did the architect have Christmas in mind? Gengenbach’s classicist town hall has exactly 24 windows, which are transformed into the largest Advent calendar house in the world during the Advent season. Every day, embedded in the wonderful Advent market in the alleyways of the old town, a new Hajek work is unveiled at the Gengenbach town hall during the window opening ritual at 6 pm.
The largest Advent calendar house in the world Gengenbach takes place from 30.11.2025 to 06.01.2026.
