The patrons of San Piero Patti are Saint Blaise, bishop and martyr, and the Madonna della Catena. Saint Blaise was bishop of Sebaste in Armenia and died a martyr in 316 under Emperor Licinius; according to legend he freed a child from a bone stuck in the throat, and for this he is considered a protector against throat ailments, which on his liturgical feast day, 3 February, the faithful have blessed with two crossed candles. The date of the civic feast was, however, moved to the first Sunday of October, since in February adverse weather conditions made it impossible to hold special celebrations: in October the traditional fair of street vendors takes place, along with popular games and shows, and in the past the custom was also tied to the sale of hazelnuts, once a thriving local product. The Madonna della Catena is San Piero's first patroness, celebrated on the first Sunday after Easter: her cult, also widespread in nearby Librizzi, originated in Palermo, where legend has it that a miracle occurred freeing some condemned prisoners through her intercession, and was encouraged in San Piero by the Orioles family.
The church of Santa Maria Assunta, a late 16th-century building, is considered among the most beautiful in the whole metropolitan city of Messina: it has a wooden coffered ceiling carved in Baroque style, with a high relief of the Assumption at its centre, while columns, arches and windows are carved in local stone. The altar of San Biagio, adorned with numerous wooden bas-reliefs, holds a statue of the saint from the school of Gagini; outside, a Romanesque arch joins the church to the majestic bell tower, over thirty metres tall and enriched with windows carved in Baroque style.
