This day celebrates the titular saint of the Oratory of San Vincenzo and San Gaetano, in the parish area of the small town of Casciana. The cult of the saint was transferred from the oratory, intact but defunct, to the parish church and it is there that he is celebrated on the Sunday afternoon, with Mass inside and then more social events outdoors.
