The patron of Zero Branco is the Assumption of Mary, celebrated on 15 August in the Church of Santa Maria Assunta.
The town's ancient colmelli districts are still recalled today in the characteristic Colmelli Tournament, pitting the inhabitants of the various neighbourhoods against each other. Along the pedestrian street in front of the church stands the central Palazzo Sagramora, a historic building of the town. The town also holds Villa Guidini and the Church of Sant'Alberto.
