Аннотация:This article considers the methodology and results of complex studies of religious buildings within the framework of the historical-cartographic and toponymic approaches to solving interdisciplinary scientific problems. Geoarchaeology and historical geography are positioned as adjacent and interrelated scientific disciplines aimed at comprehensive studies of both individual heritage sites and the knowledge and reconstruction of the evolution of regions and geographical space overall. We present the results of a detailed study of the relationship between toponymy and Christian architectural monuments based on the case study of ecclesiastical names of North-Eastern Rus’ (European part of Russia). We also provide an interdisciplinary analysis of a specific object of historical and cultural heritage (an Orthodox church in Northern Moldavia).
