Carved portals in the Annunciation Cathedral were executed by Italian makers in the early XVIth century, perhaps, at the time of construction of the new Grand Prince's palace. White-stone walls were decorated with fretwork of delicate workmanship. Images of dolphins, sphinxes, ornamental pattern in the form of vases, lamps etc. were very popular in the Renaissance. Presumably, wall painting of the portals was multicoloured till the XVIIIth century.
Two-leafed doors of the north and west portals date from the late XVth—early XVIIth century. The leafs of the door were decorated with golden foil, scenes of the Annunciation, images of the Old Testament prophets and antique philosophers.
The floor made of multicoloured quarry tile is considered to have been 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.
