Anyone getting interested in sanctuaries in Iron Age Thrace, will be struck by the contrast between Greek and Bulgarian literature on that subject. The discrepancy can be explained by the tendency in Northern Greece to study areas around Ancient Greek cities, whereas Bulgarian projects focused on sites without any Greek material are numerous. This opposition is even more striking as we consider cult archaeology. There isn't any study on indigenous cult places in Aegean Thrace, whereas in Bulgaria, several works were recently published addressing that subject, and a database is in the making. We would like to show, through a historiographic study, how contemporary administrative limits came to match with such an archaeological border. We will also suggest other criteria to analyse the local archaeological sites, hoping to enrich our understanding of cult practice, and, more widely, of settlements' dynamics in Iron Age Thrace.
