Abstract: The subject of the study is the role of large industrial enterprises in the daily life of Sevastopol in the early 1980s on the example of the Sevastopol instrument-making plant "Parus", since 1980 renamed the Sevastopol instrument-making plant named after V.I. Lenin. The authors motivate the choice of this enterprise as an example and object of research by the fact that the plant was one of the most significant enterprises both for Sevastopol and for the entire instrument-making industry of the Soviet Union. Based on archival sources, the authors consider in detail the specific episodes of the plant's activities that influenced the lives of citizens and the appearance of the city. In particular, the article discusses the activities of the plant for the construction and commissioning of residential buildings and infrastructure facilities, the organization of children's leisure. In addition, the authors tell about the activities of the enterprise itself to improve the working conditions of workers, as well as about the work of the Komsomol organization. The authors come to the conclusion that the instrument-making plant "Parus" played a significant role in the life of Sevastopol, especially one of the districts of the city - the Northern side: the enterprise developed and demonstrated success, created new jobs, expanding the range of products, and improved working conditions. Thanks to the plant, new residential buildings (apartment buildings and dormitories), kindergartens, shops, a library, and infrastructure facilities were built. Most of these buildings on the North Side of Sevastopol exist and are still used for their intended purpose. Also, the authors, relying on archival sources and, above all, reports of office documentation, state that much attention was paid to children's leisure, health improvement and education.
