The City of Cologne is opening up its art space at Ebertplatz and, together with students from the TH Köln, will be transforming it into an experimental lab for participative and post-automobile urban visions. Currently, we are observing a change in urban transport policies, freeing up automobile spaces for alternative uses. Straßenland explores the potential of such spaces, using the example of the Nord-Süd-Fahrt in Cologne.
