The church of San Rocco has a single nave and square plan, plus a presbytery also with a square plan, all the spaces are frescoed with stories from the Bible and the Gospels as well as scenes recalling the wedding of Susanna Collalto and Odorico d’Arco; most of the original frescoes, by Dioniso Bonmartini and Gaspare Rotaldo, were lost following the construction of a new door and the enlargement of one of the presbytery windows. The main fresco depicts San Rocco with the dog and on the same wall is also depicted a character who is supposed to be Odorico d’Arco who greets Susanna, who had to be painted in front. Also interesting are the inscriptions present, one of which cites an exceptional snowfall which occurred in July 1506. The fact that it was mentioned in documents only from the seventeenth century suggests that in the previous century it was a private church of the counts of Arco
