During his time in Grenoble, De La Salle would regularly say Mass here for the Sisters, taking care of their spiritual needs.
About Sisters of Visitation
Located at the top of a very steep set of public stairs set into the side of the cliff, this monastery of Sisters was one of the locations in Grenoble where De La Salle would say Mass and attend to his priestly duties.
While we don't know much about his exact routine in this regard, we do know that he went there regularly, either via the steep stairs or by a more circuitous route that would have been less arduous on his increasing rheumatism.
The Order of the Visitation of Holy Mary was founded in 1610 by Saint Francis de Sales and Saint Jane Frances de Chantal. Their aim was to provide a monastic religious life for those who had neither the physical strength nor an interest in corporal austerities that were popular at that time.
They would reach God chiefly through interior mortifications and to do everything with obedience to God's Will and the greatest possible love. Their motto is "Vive Jesus" or "Long Live Jesus." They eventually started schools for girls and today have both contemplative houses and communities associated with schools.
One can only speculate as to whether De La Salle planted any seeds of educational interest during his time with them in Grenoble.
