Not far from the wijngaarden and Chemin des Ânes/Ezelsweg, Saint-Josse-ten-Noode/Sint-Joost-ten-Node offers, between the notes of a violinist and a timeless singer, a former observatory, the souvenir of a hydraulic system for pumping water that was key to the capital’s success. The municipality has even named some of its streets in its honour, such as Rue du Moulin/Molenstraat (water mill street) and Rue Hydraulique/Waterkrachtstraat (hydraulic street). This walk will bring to life a past that urban development and population growth has almost made us forget. It will recall the great men of physics and botany, Quetelet and Houzeau de Lehaie. You will be immersed in the artistic world of Madou and the municipality’s workshops before finishing up in the Notre-Dame aux Neiges Quarter with its cold stores.
