The patron of Arzignano is All Saints, celebrated on 1 November, the day on which the traditional Fiera dei Santi is also held.
The inhabitants of the hamlets of Castello and Tezze commemorate every year, with a historical re-enactment and a procession in period costume, the ancient «Siege of the Hungarians at the Castle». Also deeply felt is the feast of Saint Agatha, to whom one of the town's churches is dedicated. Arzignano also holds its own castle, the cathedral and the church of San Giovanni Battista.
