An excerpt from the article 22 facts about Mont Saint-Michel
According to legend, the morning dew drew the outline of the foundations of the sanctuary, a stolen cow appeared where the first scrap of granite should have been, and an infant holding her in her arms pushed away with her feet a boulder that was blocking the road. St. Michael himself is also said to have appeared and pointed out a spring of fresh water.
