This thesis explores the possibility of using the psychogeographical method of dérive as a tool for exploration of urban sustainability. It reveals the interconnections of sustainability and psychogeography discourses on the ground of participatory research. It also discloses the niche of urban sustainability in terms of urban space theories, sustainable development, and psychogeography. It consists of two theoretical parts discussing the subject of the study and the methodology. The third part is practical. It is undertaken with the intention to examine the compatibility of the chosen method and the chosen topic. The results of conducted dérive in the case study city of Olomouc, Czech Republic prove that the method can effectively be used for exploration of urban sustainability and therefore has a potential to serve as complementary tool in sustainable urban planning for identification of problematic places, spaces with an unfulfilled public realm potential or even spaces city currently lacks.This thesis explores the possibility of using the psychogeographical method of dérive as a tool for exploration of urban sustainability.
