Streams are defined as dynamic, impetuous, and highly changeable over time natural elements. Interpreting the given site as a transmuting landscape, our design team proposed the construction of a linear park along the river-bed containing transient, changeable uses and flexible activities. A flowing “labyrinth” of uses and events is composed: sites with periodical exhibitions, outdoor markets, leisure activities, multi-use buildings, installations, playgrounds, open-air theatre and a central square which changes its form and use accordingly to the volume and flow of the water of the stream.
