The patrons of Malonno are Saints Faustinus and Jovita, celebrated on 15 February in the Church of Santi Faustino e Giovita.
In the past, for the patronal feast, the poor beggars were invited to the table; it was also celebrated with the «macchina» of the Triduo dei Morti, a processional structure dating back to 1771 and restored in 1985. The town also holds Palazzo Celeri-Martinengo and some rock carvings.
