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.

Proponents of the Hungarian hypothesis point to the geographic proximity and close political connection of Galicia and the Kingdom of Hungary, and the rapid development of Romanesque architecture in the latter due to French influence.
[2] The organic conception hypothesis suggests considering the Galician school as a part of the pan-European process of the development of Romanesque architecture, when similar styles arose contemporarily throughout the continent.
