The role of light in formation of a traditional image of architectural space

The natural sun light has always been an active factor in formation of local architectural traditions. The sun path impacts the settlement planning, building architecture, and interior zoning, comprising main elements of the architectural identity. In the folk architecture, the light played a symbolic, compositional or decorative role. In particular, eastern orientation of the altar in Ukrainian churches added symbolical lighting effects to the interior, while reflection of the sun light on church domes emphasized the magnitude of the building. The traditional south orientation of the front façade of houses actually resulted in a colorful, irregular composition of the Ukrainian village, contrast coloristic image of buildings and distinctive image of the scenery. Since the architecture of the Eastern European region is closely connected to the landscape, with the light as one of the main elements, its role in formation of the regional identity should be evaluated appropriately.
