The castle mound of Lossow was built as a fortified settlement in the late Bronze Age (10th century B.C.). After a use phase of ca. 200 years, a supra-regionally significant, early Iron Age cult center developed on this site (8th-6th century B.C.). Several pieces of evidence indicate that the site of the finds had a central-site character. This evidence will be explicitly elaborated and presented. So far, there is no knowledge about central-site functions in dependence on the settlement-historical and natural-spatial surroundings. But the inventory of archaeological finds offers great potential for not only a complex, but also a complete, consistent investigation and analysis of the three interrelated components: central site – open settlement spaces – accompanying fields of graves. Also unexplored until now have been the connections between, on the one hand, the geomorphological and the natural-spatial circumstances and, on the other hand, the erection of the castle mound or the surrounding settlement and grave-field structures that arose at about the same time
