The aim of the article, defined by the author as discursive, is to give the answer as to whether within ‘revitalization’ we should distinguish the notion of ‘linear revitalization’ – not yet defined in Polish and English-language literature. The author presents the thesis that we should do so by presenting the idea, its specific character and its role. This kind of action seems to have, in the author’s opinion, a positive influence on contemporary cities regarding the growing problems that result from fragmentation and lack of physical, social, economic and ecological connectivity. The general overview of revitalization provides the basis for proving the necessity of specific solutions relating to degraded linear structures. Linear revitalization, as presented, relates to different city structures which need renewal. It may become an important tool for sustainable city development and may improve the quality of life. Theoretical deliberations, presenting the reasons, needs, ideas, draft classifications, tasks and positive effects of linear revitalization have been supplemented by some case studies from Poland and abroad. The benefits to whole city structures of carrying out linear revitalization are presented. They justify the creation of a new definition and further research. The approach presented, being in the author’s opinion the beginning of the discussion, meets the need to look for effective new methods and tools within urban revitalization, solving the problems and fulfilling the new challenges of contemporary cities.
