Abstract: The interdisciplinary field of virtual 3D-reconstruction of lost cultural heritage sites is relatively young, but actively developing both in Russia and abroad. Nevertheless, the degree of elaboration of the problems of 3D-reconstruction of various types of lost interiors of cultural heritage objects against the background of an impressive number of high-quality scientifically based reconstructions of the exteriors of monastic and manor complexes, temple structures, urban development is small. Historical interiors, as one of the main forms of spatial organization of life, are unique historical monuments that contain a symbiosis of social and individual, embodied in the culture of everyday life. Stylistically and compositionally original interiors of various buildings take a special place in historical research, increasingly attracting the attention of researchers of history and culture. Rapidly developing computer technologies create more and more unique opportunities for virtual 3D-reconstruction of historical interiors and their further preservation. The article outlines the origins and main stages of the development of the problems of interior virtual reconstruction in historical research. As a result of the research, the author summarized for the first time the history of the development of research on virtual 3D interior reconstruction, traced the evolution of the main trends and research approaches to working with the source base and problems of visualizing the results of reconstructions, highlighted the current directions for solving the problem of interior 3D-reconstruction in literature and scientific projects. The developments of the author of this article create the necessary conditions for the search and adaptation of methods of working with historical sources, visualization of the results of reconstruction and its interpretation in the context of the author's work on the creation of virtual 3D-reconstructions of historical manor interiors.
