Saint Petronius, patron with the Pentecost Fair since 1966
📅 Every year, on Whit Monday, with the Pentecost Fair since 1966
Castel Bolognese celebrates Saint Petronius on Whit Monday, in the church dedicated to him; the co-patron is Saint Emygdius. In the same period, a feast in honour of the Blessed Virgin has been celebrated for centuries, instituted as thanksgiving for averting the scourge of the plague, joined since 1966 by the traditional Pentecost Fair.
