Marvel at the size of Cathedral of Santa Maria Assunta. Fit in a service if you can or just wander around and appreciate the serenity.
You'll find this principal church in Cividale del Friuli. Once you've done all you can at Cathedral of Santa Maria Assunta, head to nearby Venica and Venica, Ponte del Diavolo, and Ronchi di Sant'Egidio Farmhouse and Restaurant.
