The patroness of Vobbia is Santa Maria delle Grazie, celebrated on the second Sunday of August. Her church is the parish church of Nostra Signora delle Grazie, in the main town, which looks down over the settlement: it dates from before the 17th century, has been a parish since 1697, and keeps a wooden statue by Maragliano.
In the middle Vobbia valley, wedged between the buttresses of a cleft rock, stands the distinctive castello della Pietra, from the 13th century: once a noble estate, an important strategic outpost on the old salt road between Genoa and the Po valley, it was restored in the 1980s with funds from the province of Genoa.
