The Byzantine opus sectile floor in the katholikon of Iveron monastery is one of the best preserved and most remarkable opus sectile floors in Athos, made as a piètre dure like most Athonite floors. Was constructed around the mid-1 11th century, probably by craftsmen from the Constantinople, as part of the 'renovations' commissioned by George the Athonite during his highly creative office as abbot of the monastery (1045-1056). .
