It is a well-known that the floor made of multicoloured quarry tile was already paved in the middle of the XVIIth century. According to the legend, mentioned in the “History of the Russian State” by Karamzin N., jasper tiles were brought from Byzantium to a cathedral in Rostov Velikiy in the XIIth century century and then transferred to the Moscow Annunciation Cathedral in the XVIth century. Researches, conducted for the last ten years, let the historians consider the very floor to be executed in the Moscow region.
