The Taintignies-Willemau water buffer basin ("Zone d'Immersion Temporaire" or "ZIT") was created in the middle of agricultural land to capture excess water from the fields, preventing it from reaching residential areas and causing flooding. The entire area is designed as a beautiful experience zone. While the boardwalks invite you to cross the water, that's clearly not the intention: a very clear prohibition sign is posted (at least during my visit, on frosty days). The dikes and grasslands are managed by sheep. In the long term, this area will undoubtedly develop into a fascinating habitat for (water) birds.

The Argales de Rieulay slag heap, the largest in the region (140 ha), has long since closed its mining page. A new story has been unfolding for several years now. That of a successful reconversion.
