Urbane Künste Ruhr is an institution for contemporary art in public space without a fixed venue. For the Grand Snail Tour, we created a trailer that is a mobile spatial setting moving across the Ruhr region since September 2024. Custom-built by the project team, the trailer offers numerous mounting points both inside and out for installations and transport. Its walls can be opened in various configurations or even function as a roof. The tour itself brings together different elements: a clear conceptual framework, a touch of Fluxus, and ample room for experience.
