Ivrea is the company town that Adriano Olivetti built differently. When the Olivetti typewriter and computing company needed to expand in the 1930s–1960s, Olivetti did not simply add factory space — he commissioned the best Italian architects of the period (Figini and Pollini, Ignazio Gardella, Luigi Caccia Dominioni, Roberto Gabetti) to design not just factories but housing, schools, cultural centres, kindergartens, libraries, and social services for the workers. UNESCO inscribed the result in 2018 as a 20th-century industrial city of outstanding universal value. Every February, the Carnival di Ivrea stages the largest organised food fight in the world: approximately 500 tonnes of oranges thrown between 9,000 people in costumes over three days. Both the architecture and the carnival are genuinely extraordinary. Turin is 50 km away. Piedmont guide
Plan my Italy trip →Region: Piedmont, province of Turin | Population: ~23,000 | UNESCO: 2018 (Ivrea, Industrial City of the 20th Century) | Famous for: Olivetti company town architecture, Carnival di Ivrea (orange battle), medieval castle (Castello di Ivrea) | Distance from Turin: 50 km (45 min by car; 1h by train)
Camillo Olivetti founded the Olivetti company in Ivrea in 1908 — initially producing typewriters, then expanding into calculators and, in the 1950s, pioneering Italian electronics (the Olivetti Elea 9003, 1959, was the first fully transistorised mainframe computer produced in continental Europe). His son Adriano Olivetti (1901–1960) transformed the company from a successful manufacturer into a specific social and cultural project. Adriano's vision: the factory not as a place of labour extraction but as a community institution — the workers' physical, intellectual, and social wellbeing as a legitimate company concern. He hired the best Italian architects and designers of the period not just for the products (the Olivetti Lettera 22 typewriter, designed by Marcello Nizzoli in 1950, is considered one of the finest industrial design objects of the 20th century) but for the physical environment of the workers' lives.
What Adriano built in and around Ivrea: the Edificio Uffici (office building, 1937, Figini and Pollini — the first modern glass curtain wall office building in Italy); the residential districts of Canton Vesco and Bellavista (housing for workers, 1940–1960); the Social Services Centre (1955–1959, Ignazio Gardella); the canteen and workers' clubs; the kindergartens; the cultural centre with library and theatre; and the landscaping of the entire Olivetti campus. The result is a coherent mid-20th-century modern city that retains most of its original fabric. UNESCO recognised it in 2018 as "an outstanding example of a planned industrial landscape."
The Carnival di Ivrea is held in February (the three days before Ash Wednesday — Sunday, Monday, and Tuesday of carnival). Its central event is the Battaglia delle Arance (Battle of the Oranges): nine teams of cart-throwers (aranceri a piedi, on foot) throw fresh oranges at teams riding on horse-drawn carts, representing the tyrannical lord's soldiers. The battle re-enacts a medieval legend (a miller's daughter who refused the lord's droit du seigneur and subsequently led a popular uprising); the allegorical content has been amplified over centuries. Approximately 500 tonnes of oranges are used over the three days; the cobblestones of the historic centre run with orange juice and the smell of citrus permeates the entire town. Spectators who do not join a team must wear the red Phrygian cap distributed at the entrance to the battle zones — cap-wearing spectators are exempt from being targeted; those without caps are fair game.
The UNESCO-designated Olivetti industrial city of Ivrea is best explored on foot with the walking map available at the Ivrea tourist office (IAT, Corso Botta 2). The key buildings are all within walking distance of each other in the Olivetti campus zone (north and west of the historic centre): the Edificio Uffici main office building (now housing various businesses, exterior visible); the ICO factory (the main production plant, 1950s, modified); the Social Services Centre by Gardella (the most architecturally remarkable building in the complex, with its distinctive curved forms); and the residential districts. The Fondazione Adriano Olivetti maintains the documentation of the heritage and coordinates visits; check fondazioneadrianobobbio.it for current guided tour availability. Entry to the historic centre and campus walk is free; guided tours of interiors by appointment.
Ivrea in Piedmont is famous for two things: the Olivetti company town (a UNESCO World Heritage 2018 industrial city designed by Italy's leading mid-20th-century architects for the typewriter and computing company's workers, including housing, schools, cultural centres, and social services); and the Carnival di Ivrea (February — the Battaglia delle Arance, a 3-day organised orange-throwing battle using approximately 500 tonnes of fresh oranges, the largest food fight in the world). Distance from Turin: 50 km, 45 minutes by car.
The Battaglia delle Arance (Battle of the Oranges) at the Carnival di Ivrea is held over three days in February (Sunday–Tuesday before Ash Wednesday). Nine teams of foot-throwers battle against horse-drawn cart teams representing the tyrannical lord's soldiers, in a re-enactment of a medieval uprising legend. Approximately 500 tonnes of fresh oranges are used. Spectators must wear the red Phrygian cap (distributed at entry points to the battle zones) to be exempt from targeting; those without caps are fair game for orange throws. The carnival attracts approximately 80,000–100,000 visitors over the three days; accommodation in Ivrea and the surrounding area must be booked months in advance for carnival weekend.
Ivrea was inscribed as UNESCO World Heritage in 2018 as the "Ivrea, Industrial City of the 20th Century" — recognised for the coherent planned industrial city created by Adriano Olivetti and his architectural team from the 1930s to the 1960s. The UNESCO citation recognises Ivrea as an outstanding example of a planned industrial landscape that integrated production buildings, residential districts, and social services in a humanist vision of industrial society — a concept Olivetti called "la fabbrica a misura d'uomo" (the factory on a human scale). The key architects: Luigi Figini, Gino Pollini, Ignazio Gardella, Marco Zanuso, Roberto Gabetti, and others who shaped postwar Italian architecture.
Ivrea is 50 km from Turin — approximately 45 minutes by car via the A5 motorway toward Aosta. By train: Trenitalia from Torino Porta Nuova to Ivrea, approximately 60–70 minutes (regional train; 1–2 trains per hour during peak times). Ivrea is also on the route toward the Aosta Valley and the Monte Bianco/Mont Blanc tunnel; it can be combined with a Turin visit and the Aosta Valley in a single Piedmont itinerary. The Olivetti heritage visit and the historic centre take approximately 3 hours; combine with a meal at one of Ivrea's restaurants and the Olivetti campus walk for a full day.
Olivetti was founded in Ivrea in 1908 by Camillo Olivetti, initially producing typewriters. Under Adriano Olivetti's leadership (1938–1960), the company pioneered Italian industrial design (the Lettera 22, the Valentine typewriter, the Divisumma calculator — all now in museum design collections worldwide) and computing technology (the Elea 9003, 1959, the first fully transistorised mainframe produced in continental Europe; and the Programma 101, 1965, considered the first personal computer). Olivetti also published books, designed architecture, ran political campaigns (Adriano ran for parliament), and supported Italian culture. The company's decline after Adriano's death in 1960 was rapid; it was eventually absorbed by Telecom Italia. The Museo della Tecnologia Informatica di Ivrea documents the computing history.

Plan my Piedmont trip →The Olivetti industrial city of Ivrea is walkable from the historic centre. Pick up the UNESCO heritage map at the Ivrea tourist office (IAT, Corso Botta 2). Key buildings: the Edificio Uffici (main office building, 1937, Figini and Pollini — the first glass curtain wall office building in Italy; exterior on Via Jervis); the Social Services Centre by Ignazio Gardella (1955–59, the most architecturally remarkable building, with distinctive curved concrete forms; on Via Jervis); the residential districts of Canton Vesco (1940s housing for workers, visible on the hillside); and the factory complex (ICO, 1950s, on Via Jervis). The Fondazione Adriano Olivetti (fondazioneadrianoolivetti.it) coordinates guided tours of the interiors; exterior walk approximately 2 hours. The worker housing is private residential; walk the streets to see the exterior architecture without entering.
Ivrea in February during the Carnival (Battaglia delle Arance) is the single most dramatic time to visit — book accommodation months ahead and wear the red Phrygian cap at the orange battle to avoid being hit. The UNESCO Olivetti heritage is accessible year-round (exterior walk any time; interior guided tours by appointment with Fondazione). Ivrea is also a pleasant day trip from Turin in any season — the historic centre with the medieval castle (Castello di Ivrea, the distinctive red brick 14th-century Savoy castle on the hill above the city) and the Cathedral (with the early Christian crypt) takes 2 hours outside of carnival. The Canavese wine zone surrounding Ivrea (Erbaluce di Caluso DOCG white wine, the specific volcanic-soil white of the pre-Alps) makes the area interesting for wine tourism in September–October.
Erbaluce di Caluso DOCG is the distinctive white wine produced in the volcanic soils of the pre-Alps zone surrounding Ivrea and Caluso. Erbaluce (also called Elva or Uva di Caluso historically) is an indigenous Piedmontese white grape variety of uncertain origin producing wines of high acidity and mineral character — a combination of citrus and floral notes with a specific volcanic-mineral finish. The DOCG zone: 73 municipalities in the province of Turin and Biella. Styles: the dry Erbaluce di Caluso (fresh, mineral, 11–13% alcohol); the Passito di Caluso (from dried grapes, sweet, golden, complex — one of Piedmont's finest traditional sweet wines); and the sparkling version (metodo classico). Tastings available at the Caluso wine road (Strada del Vino Erbaluce) or from producers in the Ivrea-Caluso zone; combine with the Olivetti heritage visit for a full Canavese day.
The Castello di Ivrea (also called the Castello delle Quattro Torri — Castle of the Four Towers) is a late 14th-century Savoy fortress on the hill above the historic centre — one of the most distinctive medieval castles in Piedmont. Built between 1358 and 1357 under Amedeo VI of Savoy (the Count Verde), the castle is a square plan with four cylindrical towers at the corners — the specific Savoy defensive architecture of the 14th century that appears in slightly different forms at Fénis, Sarre, and other Aosta Valley castles. Two of the four towers are still at full height; the other two are truncated from 19th-century artillery damage. The interior has served as a prison (1700s–1970s) and is currently undergoing restoration; exterior views and the surrounding park are accessible. The castle silhouette on the hill is visible from throughout Ivrea and gives the city its medieval focal point above the Olivetti industrial city below.
The Canale d'Ivrea is a historic canal system running from the Dora Baltea river through the Canavese plain — built primarily in the medieval and early modern period for irrigation and mill power, it still functions for agricultural irrigation. The canal system and the associated mills (some still visible as historic structures in the Ivrea municipality) reflect the agricultural economy that preceded Olivetti's industrial transformation. The Dora Baltea river itself (immediately below Ivrea, where the river exits the Aosta Valley and enters the Po plain) is known for white water kayaking and rafting — the Dora Baltea rapids below Ivrea are among the most used white water training stretches in northern Italy.
