formerly (until 1922) Corneto
Town (pop., 1991: 14,000), northern Lazio region, central Italy.
It developed out of the ancient Tárchuna, one of the chief cities of the Etruscan confederation. It was defeated by Rome in the 4th century BC and became a Roman colony (as Tarquinii) in the 1st century BC. It was moved to its present site after Lombard and Saracen invasions in the 6th–8th centuries AD. In medieval times it was called Corneto. Remains of the ancient city include the foundations of a great Etruscan temple with a group of terra-cotta winged horses that is considered a masterpiece of Etruscan art. The famous necropolis contains the most important painted tombs in Etruscan Italy.
