The Roman Empire was divided into provinces for administrative purposes, yet little is known about their boundaries and internal structures. To enhance understanding of the empire’s internal frontiers and the social, economic, and territorial organization of provinces, an international project led by the University of Zurich was initiated. In 2016, an interdisciplinary group of European scientists convened in Rome to discuss initial findings. The analysis of Roman provincial borders can be approached in multiple ways. Examining written sources reveals their importance for political and tax organization. Utilizing geographical information systems (GIS) helps visualize topographical structures and propose effective border lines, such as between Germania superior and Raetia. Investigating the production and distribution of material culture, including pottery, coins, and costumes, sheds light on economic structures and cultural practices related to provincial borders. Bioarchaeology offers insights into human diets, animal husbandry, crafts, trade, social structures, and religious beliefs through the study of animal bones and botanical remains. These various approaches highlight regional characteristics and prompt questions about spaces and frontiers in Roman provinces. The contributions are presented in a dozen illustrated essays, written in English and German.
