Only in this kind of environment, free of dogmas and self-governed - far from major governing centers - could it be possible for the artisan known as Giorgio da Sebenico "(Juraj Dalmatinac)" to build a church entirely as his own project – the Šibenik Cathedral of St James, constructed in 1441. Besides mixing of the Gothic and Renaissance styles it was also original in its unity of stone building and montage construction (big stone blocks, pilasters and ribs were bounded with joints and slots on them - without concrete) in the way that was usual in wooden constructions. This was a unique building with so-called three-leaves frontal and half-barrel vaults, the first in Europe. The cathedral and its original stone dome was finished by Nikola Firentinac following the original plans of Juraj.
