The patron of Vittuone is the Holy Cross, celebrated on the first Sunday of May, or the second if the first falls within the first three days of the month.
For the occasion a popular fair is held, and the «Order of the Holy Cross» is awarded to the parish's deserving members. In May 2012 Cardinal Dionigi Tettamanzi took part in the patronal feast celebrations. The town also holds the Church of the Annunciation of the Virgin Mary.
