Grumento Nova has two patrons: the Madonna del Monserrato, celebrated on the last Sunday of August, and Saint Laverius, on 17 November.
The second date ties the village to Acerenza, where the saint was born. Laverius died a martyr at Grumentum on 17 November 312, so on the same day he is celebrated by two Lucanian towns: the one where he was born and the one where he died.
