On 19 August Castroregio celebrates San Rocco, patron of the village.
The wedding rite (martesia) is characteristic: by custom the passage of the wedding procession through the streets of the village is announced by the 'Flamurari' (flag-bearer), a name that comes from flamurë (flag). The municipality also holds the Chiesa Madonna della Neve and the Parrocchia San Nicola di Mira.
