Between the pizza, the stories of hard-working immigrant families, the accordionist singing Nino Rota’s theme from “The Godfather,” and the big green, white and red flags, St. Helena’s inaugural Festa Italiana was about as Italian as anything you’ll find this side of Sassoferrato.

Saturday’s celebration, the first of three events marking Italian Heritage Month, drew hundreds of people to Lyman Park to share community-friendly vibes and toast the Italian and Swiss-Italian immigrants who shaped the Napa Valley and its wine industry.
