The current state of the Moscow Metro station of the first priority that became operational in 1935 does not allow it to be called a cultural heritage site. This is due to the fact that lighting modernisation carried out by the Moscow Metro was based on fluorescent lamps. Such lamps are more energy efficient compared to incandescent lamps, which were used in original lighting devices specified in the Station Lighting Project developed by architects and designers. However, they significantly changed the station appearance, transforming the originally designed station with entire well visible architectural tectonics?1 from the standpoint of lighting into a simple, flat, unremarkable, and little loaded station of the Moscow Metro./br> This paper describes a method of lighting reconstruction at Krasnoselskaya station by means of original lighting devices that meet modern standards and requirements for cultural heritage sites. The historical analysis on the development of the station lighting environment was conducted during its operation in order to understand what kind of station was conceived by its architects, what changes occurred with its lighting over time, and how it influenced the station appearance and safety of passenger transportation.
