One of the patrons of Vitulazio is Our Lady of the Agnena, venerated in the Cappella dell'Agnena and the Church of Santa Maria dell'Agnena.
The patronal feast is held starting on the Thursday after Easter, culminating in the solemn, long procession of the Sunday after Easter, in which the sacred image of the Madonna is placed on a great cart decorated with flowers. The town also holds the Chapel of San Michele Arcangelo and the Cappella Luciani.
