The article is devoted to the consideration of the concept of authenticity set forth by S. Zukin in the book “Naked City: Death and Life of Authentic Urban Spaces”. The sources of the concept are traced in the author’s early works, the main subjects described in them are: the process of gentrification; power relations forming the urban landscape; symbolic economy and the power of cultural characteristics. These subjects became the basis of the idea of authenticity. Its manifestations are described by the example of “uncommon” and “common” urban spaces. A separate place in the article is considered by the development of individual ideas of Sh. Zukin, their interpretations, as well as applications for specific studies in the work of followers. The conclusion is drawn about the variety of interpretations offered by researchers and the ambiguity of using authenticity as a tool for analyzing the city.
