The Wiels Marsh is a reserved space, a generous place for animal and plant species, around which humans can circulate and look but not enter, or only in a controlled manner. This nature is extended to new topographies, creating landscape and ecological continuity. The space is then organized “around the marsh,” which becomes the primary landscape, a permanent backdrop, a space with which to coexist and which must be respected. Around the marsh is organized a system of spaces which, together, constitute a recognizable open space, a third landscape. It is the common reference point for the site, and its central position makes it an emblematic place that is accessible from all sides yet inaccessible. The proposed intervention frames this piece of nature in the city, reinforcing existing landscape continuities and providing urban spaces for the activities already present on the site.
