The concept of a restorative city is one of the most recent and fascinating developments in the field of restorative justice theory and practice. Despite the lack of universal model or standards of implementation, the concept of a restorative city can be defined as a process that aims at shaping both community life as well as urban space through the lens of restorative justice philosophy, values and standards. The purpose of this paper is to discuss the results of the analysis of how this concept has been implemented so far in a number of selected cities, systematise the knowledge about the process of implementing the idea of a restorative city and advance the discussion around the conceptual framework of this development. The paper concludes with a brief summary of activities that have been undertaken in Wrocław, Poland, in order to gain the status of a restorative city.
