Abstract: The article is devoted to the problems of the methodology of the study of petroglyphs of architectural structures of the North Caucasus. The author considers methodological approaches to the interpretation of their semantics, taking into account the dual nature of petroglyphs of architectural structures, which, on the one hand, are a special cultural phenomenon with their pictorial traditions and a set of symbols, and, on the other, genetically go back to rock art, respectively, possessing the properties of rock paintings. The author believes that, interpreting the semantics of petroglyphs and their compositions, it is very important to take into account the historical context in which they were created and consider their significance in line with religious traditions relevant to the population of that era. According to the author, epic formulas or ideograms that originate in rock art play a special role in deciphering the meaning of petroglyphs of architectural structures, and in petroglyphs of architectural structures they acquire a specific character due to a narrow set of sacred symbols. The methodological basis of the research is a set of general historical, ethnographic and archaeological research methods, the use of which is determined by the nature of the material being studied. The author believes that, despite the difficulties of interpreting petroglyphs of architectural structures associated with the reconstruction of religious and mythological representations of the ancient population, it is a certain set of sacred symbols and their compositions, as well as epic formulas, that are the key to their deciphering. Petroglyphs of architectural structures have their origin in ancient rock art, which makes it possible to use in their research, including methodological techniques for studying rock paintings, the historiography of which has almost 150 years and a huge number of scientific monographs and articles. At the same time, the petroglyphs of medieval buildings in the North Caucasus possessed expressive self-sufficiency, which allowed the peoples of the region to use it to fix their religious, mythological and social traditions for transmission to the next generations.
