Why come
Castelnuovo di Porto sits on a tufa spur between the Chiarano and Mola valleys. The first fortification went up before the year 1000 under the senator Alberico, and the medieval village grew around it in concentric loops that still shape the centro storico today. The Colonna family took the fief in the late Middle Ages and built the fortress that occupies the highest point of the ridge, the keep from which the whole settlement takes its layout, houses and passages stepping down the slope in rings.
The town's name preserves its administrative link to the river: this was the Castrum Novum of the bishop of Porto, the old diocesan seat at the Tiber mouth, a naming that ties a tufa hilltop village to an ecclesiastical authority seated on the coast. The Borghi più belli d'Italia membership covers the centro storico and the fortress together, while Etruscan and Roman archaeology runs through the Veio park that surrounds both. The result is a village whose name records a bishop's jurisdiction, whose form records a medieval defense, and whose surroundings record two much older civilizations, all still legible on the same ridge.
