The thesis presents the catalogue overview of the sacral architecture of the early medieval Cetina County from the Late Antiquity to the Early Middle Ages. This territory encompasses upper and middle course of the Cetina river, that is, present-day towns of Sinj, Vrlika and Trilj and municipalities of Kijevo, Civljane, Hrvace, Otok and Dicmo. The introductory chapters include a review of previous archaeological researches within studied territory; a short description of geographical and historical characteristics of Cetina County; an overview of ecclesiastical organization of the area from the emergence of Christianity to the 11th century and a brief review of Roman residential-economic complexes. The catalogue presents the analysis of the late antique and the early medieval sacral buildings and their stone sculptures. Also, each catalogue entry contains a review of hitherto published literature on the topic and a brief conclusion based on the given information. The territory of Cetina County is an archaeologically rich region, however it hasn't been sufficiently researched yet. Based on the catalogue analysis of the sites and their contextualisation through geographical and historical features of the area, but also with the help of the maps that accompany this paper, the conclusion proposes the interpretation of the cultural and historical landscape transformation of the present-day Cetina region and a commentary on the potential future researches.
