The present article displays the results of the pilot research of the mapping of public spaces by the ethnic-Russian youngsters. Using the methodology of Kevin Lynch, seven young persons from the Russian urban communities created mental maps of beloved places in Chisinau. The goal of this study was to test this research tool and to identify the features of these spaces. The research demonstrated that the third places are the most preferred spaces, where most of them are green areas that are an escape from the urban life. As research tool, the mental maps proved to be a vivid and deep empiric material that can offer rich information about the urban life of young people.
