The aim of the work is to study the mechanisms of constructing communicative memory of the residents of modern villages of Hrushivka (Apostolove District, Dnipropetrovsk Oblast) and Kapulivka (Nikopol District, Dnipropetrovsk Oblast). The settlements under research are directly connected with the location of the Bazavluk (1593-1638) and Chortomlyk (1652-1709) Siches on their territory and realization of one of the large-scale Soviet economical experiments – the program of general electrification, leading to creation of artificial seas and construction of hydroelectric stations. Research methodology.Proceeding from modern methodological approaches in the sphere of memory studies, instruments of oral history, generalizations of fragmentary regional studies, the interrelation of national meta-narrative with the local history was analyzed. The article employs methods of filmography, which potentiated the definition of both the official directions and assessment of the Soviet transformations, directly connected with the territory and certain localities the article deals with, and the local population’s attitude towards these processes, engaging available scripts, documentary and feature films of the 20-ies - 50-ies of the XX century. The methods mentioned above and their implementation stress the novelty of the research. Conclusions Seas need territories, which in this case were taken from people. Destroyed villages and flooded cultures, churches, other unique religious buildings, natural phenomena became the objects of memorialization and communicative memory of the residents of mentioned locations. The article discovers the ways of “imprinting” of the general political situation in the country on the regional contexts of remembering, which have been adapted / fit into a new nation-scale myth since early 90-ies of the XX century, providing the Cossack pages of history with a prominent role. The formation of a new historical narrative in the early 90-ies and the corresponding model of memory, its communicative version received additional incentives for preservation and adaptation to the demands of the time. Thus, the memory of the past, with corresponding memory codes, and the “glory” of the villages of Hrushivka and Kapulivka are used from the standpoint of the present.
