The interaction between cultural heritage and tourism is characterized by a long continuity and increasing intensity of mutual relations. This relationship and dynamics have been well studied and confirmed both theoretically and practically. However, the fact that is less recognized, researched, and respected, particularly in the case of foreign tourism, is considerable potential for enhancing complex relations in international cooperation. Serbia has long been recognized as a mosaic of spiritual and material culture from various epochs, with characteristics and influences from its immediate and wider surroundings (ethnic, religious, ideological, political). This paper focuses on Russian (Soviet) cultural heritage in Serbia. With all its spatial, temporal, and thematic differentiations, it significantly contributes to the overall cultural heritage. The most significant frequency, diversity, recognizability, and spatial presence were "imprinted" during the first half of the 20th century, but with varying intensity, it can be traced back almost a thousand years to the present day. This segment of cultural heritage represents significant potential for improving bilateral, as well as overall regional and international relations - tourism development, cultural exchange, economic, and political perspectives. This topic certainly has growing importance in the context of the current geopolitical situation. Russians are rediscovering Serbia as a desirable destination for tourism, spirituality, economy, and in every other context for both short and long stays.
