The patron of Mezzago is Our Lady of the Assumption, celebrated on 15 August in the Church of Santa Maria Assunta. The same patron is celebrated a second time on the third Sunday of September.
The town borders the Adda Nord Park and the Parco Agricolo Nord Est. In May, the traditional Asparagus Fair is held, established in the 1950s, culminating on the day known as «mezsvago», heir to the historic spaventamaggio tradition.
