In the age of globalization and technological progress, abandoned industrial complexes are valorized for the purpose of conversion. In Croatia, the importance of these spaces is not recognized, as such they are falling into disrepair. Industrial heritage is important for understanding urban development and the identity of cities, it encompasses architectural, landscape, and social aspects. The work deals with the analysis of historical maps the current state of the wider urban space, and transformations of industrial zones, with a special emphasis on the Žitnjak industrial zone in the city of Zagreb. By collecting and analyzing data from different sources, the history, current state, and future potentials for the development of the zone are investigated, along with a comparison with international revitalization practices. The purpose of this paper is to point out the importance of protecting industrial heritage by showcasing the importance of green corridors in the urban matrix and raising awareness regarding the issue, all with an emphasis on the integration of sustainable (ecological) design and the preservation of cultural and historical values. This work focuses on and elaborates possible guidelines for the revitalization of brownfield areas, by forming new elements at those locations with the goal of building a new identity of the space.
