the swampy underground of the site and its medieval fisherman tower inspired people to gather scientific information to nourish the emerging micro-initiatives. Hydrological, geological and historical maps of the area were brought together and compared in order to get a better understanding of the landscape, biodiversity and heritage. Engravings and histories were exposed on the billboard, the old river bed and ponds located on a map in order to look for ground water through drilling and ground sampling. In short notice, an impressive amount of collective knowledge is being gathered.
