Although both examples of capital cities are relatively similar in geographical position and ha ve similar history and tradition at first glance, it would be very helpful and necessary to mak e comparative research that will show a realistic picture of both cities. Previous studies sho w, the similarity in some of the most important social phenomena has been significantly lost. For example, in the area of quality of life and housing and the equipment of the immediate s urroundings in which residents live everyday life, then also in the field of environmental prot ection and the existence and accessibility of public spaces and institutions, as well as in the field of participation of citizens and civil society and cooperation with city institutions – there are differences in all these fields, but it is clear that Ljubljana has made significant progress in all these areas compared to Zagreb. Therefore, the participating institutes will become mo re familiar about all of these fields during their visits. The goal and purpose of the continuati on of the research is to study the methods and modes of the work in the Ljubljana case of r evitalization, which could be used for the benefit of all its inhabitants in the center of Zagreb and the city as a whole. Positive revitalization of the city center on the example of Ljubljana is reflected in the increa se and accessibility of open public spaces. Such developmental practices are characteristic for developed western cities, but they need to be used for cities in transition, such as Zagreb still is. In addition to the advantages that such a development brings to the city, the particip ating researchers of the Urban Planning Institute of the Republic of Slovenia will also presen t to their colleagues from the Institute for Social Research weaknesses of such development. By increasing the attractiveness of the city center and the tourist development, the city cen ter is becoming less attractive and affordable as well as inaccessible for the inhabitants. The process of gentrification that is being successfully managed by some cities in Western Europ e is happening in Ljubljana. The Slovenian researchers will also present what happened duri ng the years of the rapid development of Ljubljana's city center outside the city center itself. For the rest of the urban areas, less attention (and resources) was paid, despite the fact th at the largest share of the urban population resides in these areas.
