The urban public space is permeated by structures that serve to influence human thinking and behavior. Some of these structures affect all people who move in public space. Others affect only marginalized groups such as homeless people or addicts, but also young people are particularly affected. We have become accustomed to many of these structures, so that we do not consciously perceive them and therefore do not question them. Some are more subtle and others are symbolic in nature. This work tries to understand these structures as a representation of power and hegemony in the public space and to discuss them critically.
