Around 500 BC the Etruscans founded Kainua - "the new (city)" - with a complex religious rite of which the stone with a graffiti cross located in the center of the city is testified. Kainua prospered thanks to its strategic position along the river Reno, an important commercial route between northern Tuscany and the Po Valley. It was abandoned in the mid-fourth century. BC, coinciding with the descent of the Celts in Italy. In Roman times the area of the Etruscan city was now countryside, remaining so until its rediscovery in the nineteenth century. The urban layout develops around a wide north-south road axis intersected by three east-west roads. A series of minor streets defines narrow and elongated blocks within which houses and artisanal plants arise. The north-eastern sector of the city hosts two large temples dedicated to Tinia and Uni, the main deities of the Etruscan pantheon. Monumental sacred buildings also rise on the acropolis hill, now accessible through the bridge on the SS64 Porrettana. To the east and north of the urban area there are the necropolises, of which numerous burials remain surmounted by funerary signs of different shapes and materials.
