The UNESCO series: Ivrea, industrial city of the XXth century

Despite being a very beautiful town, founded by the Romans (whose trace are still today visible in the roman bridge over the Dora Baltea river) under the name Eporedia, and despite being the birth place of Arduino, a man who was crowned the first king of Italy in 1002 (whose castle is still towering on the hill above the city), Ivrea has been a hub of the modern industrial production for a long period of time, spanning from the early 1900s up to the 1980s. Many city have an industrial past so why should Ivrea count more than others? The Unesco Committee provides us with the response.
