The legend is about the initiative of three brothers who set about building the castle.They worked all day, but the walls fell down at night. They met a clever old man who advised them to sacrifice someone so that the walls would stand. The three brothers found it difficult to decide whom to sacrifice. Finally, they decided to sacrifice one of their wives who would bring lunch to them the next day. So they agreed that whichever of their wives was the one to bring them lunch the next day was the one who would be buried in the wall of the castle. They also promised not to tell their wives of this. The two older brothers, however, explained the situation to their wives that night, while the honest youngest brother said nothing.
The following afternoon, the brothers waited anxiously to see which wife was carrying the basket of food. It was Rosafa, the wife of the youngest brother. He explained to her the agreement that they had made, namely that she was to be sacrificed and buried in the wall of the castle so that they could finish building it. She did not protest.
The faithfulness of the youngest brother and the life sacrifice of his young wife are portrayed as elements of symbolic importance. Rosafa, who was predestined to be walled in, worried about her infant son, accepted to be walled in on condition that they leave her right breast exposed to feed her newborn son, her right eye to see him, her right hand to caress him and her right foot to rock his cradle. It is said that milk still flows from one of the walls in the castle.
