The patron saints of Plodio are Saint Andrew the Apostle and co-patron Saint Anne, celebrated on 26 July. The parish church of Sant'Andrea, in the town's oldest hamlet, is an 18th-century Baroque reconstruction of an earlier 16th-century building. The chapel dedicated to Saint Anne and Saint Lucy, in the locality of Colla, instead dates from the 16th century and was remodelled in 1642 and in the following two centuries: it has a small portico and a bell-gable.
Next to the parish church stands the oratory of the Confraternity of the Guardian Angels, damaged by Napoleonic troops during the clashes of 1796 and today converted into a theatre, which preserves a 1731 bas-relief above the facade portal. The town also preserves the Bric Tana Regional Park, with the Masso altare and the masso croci, testimonies of an ancient popular devotion linked to this territory.
