The patron of Cividate al Piano is Saint Nicholas of Bari, celebrated on 6 December in the Church of San Nicolò.
In his honour, from the sixteenth century to the first half of the nineteenth, the important Fiera di San Nicolò was held every year from 6 to 13 December. The town also holds the Shrine of the Beata Vergine Addolorata dei Campiveri.
