The patron of San Zeno Naviglio is Bishop Saint Zeno, celebrated on 9 December in the church of San Zenone.
Since 1982, in the first days of September, the Palio delle Contrade has been held, organized by the Oratorio. In the parish sacristy, a bone fragment of Deacon Cesario is kept, set in a carved and gilded wooden urn reliquary. The town also holds the Church of Santa Maria Assunta.
