One of the most fascinating monuments of the Balkan prehistory are Bronze and Iron Age burial tumuli, many of them used as grave places throughout later history and even until recent times. They represent a perfect example of a cross-border cultural heritage in the Balkans which has yet not been properly assessed in terms of visualization and communication. However, a number of tumuli is not visible on the surface due to destruction and only geophysical screening and intensive surveys can detect them. In the frame of the project, we will focus on large earth made tumuli in northeastern Bosnia that represent one of the earliest monuments of this kind in the region.
