Upper and lower churches on mount Anakopia: experience of virtual reconstruction of architectural decoration

Introduction. The article is devoted to the virtual reconstruction of two churches on Mount Anakopia in the Republic of Abkhazia. The project to create three-dimensional models of two churches was preceded by a long period of study of sources of various kinds (archaeological, ethnographic, historical, iconographic, etc.) using complex research methods (iconographic and stylistic analysis, etc.). Methods and materials. In the summer of 2023, additional field research was carried out (ground-based photogrammetric survey, aerial photography, terrestrial laser scanning, etc.). As a result of photogrammetric processing, a surface triangulation model of the Upper and Lower Church, as well as orthophotomaps and digital models of their surfaces, were obtained. Analysis. The data obtained made it possible to create three-dimensional models of the Upper and Lower Churches, as well as, separately, fragments of their architectural decoration.
