The Bellastock festival brings together 400 participants each year in the same place, to imagine, build and live in an ephemeral city on a scale of one for 4 days. This large collective open-air project is accompanied by a rich cultural and musical program, which combines theory and practice to explore the new ecological and social practices that Bellastock has been promoting since 2006.

In 2023, the Bellastock festival chooses to explore learning by doing , in construction and architecture as every year, but also in all areas relating to the arts, landscape and heritage.
