Among the most emotionally expressive decorations of the church, the metal bas-reliefs framing the main entrance gates stand out for their refined beauty. Based on religious subjects as well as on battle scenes, the plastic volumes of the portrayed figures pleasantly contrast with the even background, delivering an intense emotional impact. Despite the huge scale of the work, being the main gate 7m wide by 12m high, and the intensity of the artistic portrayal, the global layout delivers an unexpected visual lightness.
The impressive dimensions of the entrance gates, along with their volume, colour, texture, and spatial location had to be considered while developing a befitting lighting concept carried out under the direction of Mikhail Fayantsev. Moreover, general issues concerning the correct luminaires placement, the existing legal restrictions, installation mode, electrical connections, technical requirements, and maintenance operations had to be taken into account to specify the right lighting system.
