Cultural assets in the area of the Danube Limes in Serbia are an integral part of the world heritage “Roman Empire Borders”. The research presented in this paper includes the tourist and cartographic visualization of 19 Roman sites in the Danube Limes region of Golubac–Radujevac, to determine the real possibilities of tourism development in this area. The historical and cultural heritage of this area is among the most attractive tourist destinations in Serbia, Djerdap National Park and Djerdap Geopark. Despite its diverse cultural and historical values and the specific and unique natural environment, this area is not sufficiently used for tourism. The research included the evaluation of localities, which may serve as the basis to establish which activities should be undertaken in order to plan, use, preserve, and protect such important cultural assets, under the principles of sustainable tourism development. Information based on spatially referenced data in the research process requires cartographic support, in order to understand the geospatial relations of the site significance. Cartographic visualization enabled efficiently systematized data organization, spatial identification, presentation, and the use of complex information from the mapped area in the data analysis in this paper.
