Since 2011, the neighbouring cities of Basel-Stadt, Weil am Rhein, Huningue and Saint-Louis have been working towards the shared goal of developing a crossborder urban district between Dreirosen Bridge and Palmrain Bridge. They are actively shaping structural change. The outstanding potential for urban, transport and leisure space development creates a trinational challenge that is unique in Europe.

The 3Land project is a literal implementation of the IBA Basel 2020 motto “Growing together across borders”.
