The city of Marl (Germany) is experiencing a critical moment. While the coal industry once brought widespread economic prosperity, it has now left behind a heavily impacted landscape: pollution of surface and groundwater, destruction of flora and fauna habitats, soil contamination and impervious surfaces, subsidence, industrial decommissioning, and economic and social emergencies. However, the crisis also contains the potential for renewal and transformation. The Auguste Victoria Mine and 3/7 Chemiepark arose at a time when heavy industries needed to be separated from the city. The green spaces and landscape acted as a buffer between residential areas and industrial sites. The closure of the Auguste Victoria Mine 3/7 offers an excellent opportunity to rethink not only the site itself but also to redefine the new focal point and future direction for Marl. The Auguste Victoria site can become a hub that guides the city toward the Lippe River and promotes sustainable development based on ecology, energy production, and knowledge. We believe Marl and its surrounding landscape hold immense potential, and that the future can be built on three main pillars, representing three integrated scenarios: a tourism city, an energy city, and a city of production and knowledge.
