The Pryazhka team conducted their research in the historical center of Saint Petersburg. The object of their study was the Pryazhka river, which flows in the district of Kolomna. The peculiarity of this river is that it combines both urban and natural features. Unlike other rivers that flow in the center of the city, there are no stone retaining walls and parapets; people here fish, feed birds, walk dogs, sit on the grass, swim. However, the idyllic image of the river is hindered by the large number of abandoned and dilapidated buildings located around, which allows local residents to call the Pryazhka as an unsafe and even marginal place. Thus, the Pryazhka team tried to figure out who are the people who come to the river, what do they do here, how do they feel about it, and how do they imagine the future of the river coastline.
