Batolabo is a travelling laboratory navigating Europe’s rivers, from the Loire to the Danube, aboard a traditional wooden boat. Launched in September 2025 from Orleans, this river-based laboratory explores ways of inhabiting waterways and assessing their health through an artistic and scientific protocol developed along the water, inspired by river cultures. It aims to amplify the voices of rivers and highlight a unifying continuity between European watersheds, while fostering civic engagement.
