The fame of the chapel spread from the twelfth century especially because of the many miracles of the Virgin. The pilgrimage to Notre-Dame quickly gained momentum, encouraged by the Church which granted, or sold, indulgences to the pilgrims. In the 17th century, these pilgrimages took a particular form. Here were brought the stillborn children, who were resuscitated for a few moments, the time to baptise them and thus ensure the salvation to their soul.
