Promenade des Artistes – Pouhon Delcor – Promenade Cherville The city of Spa and its forests inspired many artists in the 19th century. The Promenade des Artistes was dedicated to them. The trail was inaugurated in 1849. It follows the valley of the Picherotte, a small stream that runs down from the wooded hills. At the beginning of the trail we find one of the many capture points of Spa Monopole, the company that has been bottling and exporting the communal mineral waters since 1921. A discussion on common property and use rights of the waters extended here to the right to immaterial goods and services, like the arts.
