-Spa became renowned for its medicinal water as early as the 16th century. The city embodies a history of four centuries of exploitation of springs which deliver ferruginous water with curative properties and, later, table water. This walk took us to the origins of the water, the Fagne de Malchamps. The morphology of the Fagne (‘peatland’) creates conditions for generous rainfall that is absorbed by the soil. It is the start of a long journey before the water resurfaces in one of the sources that surround the city. Walking towards the Fagne via Promenade des Artistes, we reach the Source des Artistes and one of the water capture points of Spa Monopole. As this promenade is conceived as a 19th century artificial landscape, it needs special care for its specific form to be preserved as part of the city’s heritage. Stepping in the footsteps of those who came before invited a reflection on the ecology of art and the water.
