In the heart of downtown Saint-Denis, topped with red peas of a mushroom and containing an unbuilt land, the Swan Islet is an exceptional place, vestige of our past. Nature grows there in complete freedom, between the old stones and the bed of an old stream. This site has hosted a dense and diverse life over the centuries, which is just waiting to be told…. In a context of climate change and ecological emergency, Franciade invites you to meet us at this place, a crossroads between present and past to visit it and take a look back at the activities carried out in July around heritage and ecology.
