Along the pathways and amidst the trees are forty-one grottos and religious sculptures dotting the landscape of the 120 acres of the Sorrowful Mother Shrine. Each grotto is dedicated to a saint or a mystery of Christ’s or the Blessed Virgin’s life. Pilgrims may visit and pray at all the grottos or choose to hold special services at grottos honoring saints to which they have specific devotions. Each year pilgrims form processions to visit the grottos and honor their patron saints.
