The article deals with the subject of greenery aestheticization understood as upgrading of functional and spatial attractiveness of public green areas within a process of socialized planning. The most important issue is to emphasize the role of social participation in the process of transforming green areas that are degraded or insufficiently defined, striving to create green infrastructure systems both in the context of providing the most desirable spatial offer and the greatest social satisfaction. An important element of the presented considerations is also the perception of the urban landscape in terms of interdependence and coexistence of anthropogenic and natural elements, as well as spatial, social and semantic values. This article presents the author’s experience as part of placemaking activites on the example of the Old Warta River bed in the central part of the city of Poznan.
