Treia is a municipality located north of the Potenza river valley. The center of the village is the Piazza della Repubblica with its public and religious buildings. The specialty of Treia is the “calcione”, a typically Easter dessert with a cheese filling, to which a festival is held which takes place in May. Between the end of July and the beginning of August, the historical re-enactment “Disfida del Bracciale” is unmissable.
