An unusual witness to local history, the Sézanne Pâtis, located on the edge of the city, tell how, more than a century ago, human activity shaped these spaces.
But above all, they are home to an exceptional natural heritage: callus heaths, pools with remarkable aquatic plants, dragonflies and amphibians, like the very rare crested newt, whose male has a dorsal crest that makes it look like a small dragon.
Come and discover this biodiversity hotspot listed in the European network Natura 2000, in the company of an animator of the Conservatory of Natural Spaces of Champagne-Ardenne.
