Urban renewal in derelict sites has become a focal point of interest in many traditional industrial cities. Having adopted the case study of the Cork City (Ireland), the authors presented four urban renewal schemes which were implemented in this city over a 25–year period. It ought to be emphasised that not only has Cork implemented various rejuvenation programmes since 1979, but also revived three entirely different urban sites: the former industrial areas, the historic centre and the docklands. However, the latter still requires further regeneration. The urban renewal schemes contributed to an enhancement of the quality of life and a rise in local and inward investment. Moreover, the number of tourists increased considerably. In consequence, the image of the city was improved. Hence, the urban renewal has become a factor of Cork’s redevelopment.
