Galician school is a style of Kievan Rus' and Romanesque architecture that developed on the territory of Ciscarpathia during the reign of Rostislavichi of Galicia. It was the main style of monumental, especially sacral, architecture in the Principality of Galicia. The characteristic feature of the style is the use of Romanesque masonry technique of cut white stone blocks to create cross-domed churches of Byzantine type. It is believed that the builders of the Galician school built the first stone churches of the colonized Zalesye, which gave rise to the features of architecture of Rostov-Suzdal Land.[1][2]
