Abstract: This article discusses the evolution of the study of industrial heritage in domestic and foreign historiography. According to the Nizhny Tagil Charter of the International Committee for the Preservation of Industrial Heritage (TICCIH), industrial heritage means the values of industrial culture that have historical, technological, social, architectural or scientific significance. Despite the fact that industrial heritage has been a topic of study for more than half a century, it is still often overlooked (not included in the register of cultural heritage), which sometimes puts industrial monuments at risk. Interest in industrial heritage is not a momentary trend or a local topic of individuals, but a significant scientific direction for decades, deserving the attention of researchers, the public and the state.
Post-industrial development, characteristic of the XIX century, leads to the completion of the life cycle of a large number of industrial objects, which turn out to be unclaimed due to changes in production processes and, therefore, the loss of their original functions by objects. The question of how the future fate of the former industrial buildings should develop remains open.
Therefore, it becomes important and necessary to collect and comprehend many years of experience in interdisciplinary work in the field of studying and preserving industrial heritage. Attention is also paid to innovations in this field, such as the use of virtual 3D-reconstruction and virtual reality technologies in the study and preservation of industrial monuments, which became possible both due to the rapid development of technologies and a large amount of work carried out by researchers to integrate these technologies into scientific research.

Abstract: The article virtually reconstructs the historical appearance of Moscow Tryokhgorny Brewery production building in the late 19th and early 20th centuries. Through the decades, Tryokhgorny Brewery held the leading position in the brewing industry of both the Russian Empire and the Soviet Union. This study describes virtual 3D-reconstruction methods applied, addresses the issue of using various source types (narrative, graphical and photographic materials) and considers the issue of data incompleteness. It briefly describes the history of Tryokhgorny Brewery and the subject of research and preservation of industrial heritage. The source base gathered led to the conclusion that its informative potential is enough for creating scientific virtual 3D-reconstruction. As a result, the renders of virtually reconstructed “Varnya” production building were created in Unreal Engine 4 software. In 2006 Tryokhgorny Brewery stopped working and turned into a possible industrial heritage object as its main buildings were constructed in the late 19th century. Historical research and virtual reconstruction of Tryokhgorny Brewery are specifically topical today because despite its importance as an object of industrial heritage it is in danger of complete destruction.
