Ivrea, industrial city of the 20th century

Ivrea is a planned industrial town in Piedmont, northern Italy, whose 20th-century urban fabric is closely associated with the Olivetti company founded by Camillo Olivetti in 1908. The site represents an ensemble of factories, offices, housing and civic buildings that illustrate industrial-era town planning.

The ensemble includes company factories and associated workers’ housing, civic buildings and public spaces laid out on a coordinated plan; the scale is municipal rather than a single building. Highlights are the relationships between industrial complexes and residential neighbourhoods and the presence of modernist and functionalist architecture across the town.

The site was developed by the Olivetti firm over the 20th century to serve manufacturing, administration and the workforce, with major construction phases during the interwar and postwar periods. Over time buildings and urban blocks were adapted for changing industrial uses while retaining the planned layout and many original structures.

Ivrea sits in the Canavese plain at the southern edge of the Alps, on the Dora Baltea river. It lies in northwest Italy within the Piedmont region, roughly 50-60 kilometres north of Turin, surrounded by agricultural land and foothills.

• Olivetti connection: Many buildings, factories and worker housing were commissioned and maintained by the Olivetti company that dominated local industry in the 20th century.
• Architectural period: Much of the townscape dates from the mid 20th century and shows planned industrial-city design rather than medieval or baroque layers.
