The Cave of Saint Ignatius is a sanctuary declared as a Local Cultural Heritage that includes a baroque church and a neoclassical building in Manresa (Catalonia), which was created to honor the place where, according to tradition, Saint Ignatius of Loyola shut himself in a cave to pray and do penance during his sojourn in the city from March 1522 to February 1523, where he wrote the Spiritual Exercises[1] returning from his pilgrimage to Montserrat.[2]
