Ivrea has two faces, both extraordinary. The first: Olivetti's Industrial City (UNESCO 2018) — in the 1950s-60s, Adriano Olivetti built a factory complex that embodied his vision of humanistic capitalism: workers' housing by leading architects (Luigi Figini, Gino Pollini, BBPR), a cultural center, a nursery, and factory buildings where the Lettera 22 typewriter (voted the best design product of the 20th century) was made. The architecture is a UNESCO-recognized masterpiece of industrial humanism. The second: the Battaglia delle Arance (Battle of the Oranges, Carnival Sunday-Tuesday) — the largest food fight in Italy, where 9 teams on foot battle teams on horse-drawn carts by hurling 500 tons of oranges at each other in the piazzas. The medieval town sits above both: the Duomo (11th century, Romanesque — Roman columns, frescoed crypt), the Castello (14th century, red brick), and the Torre di Santo Stefano. Piedmont →
Plan my Piemonte trip →Olivetti Complex (UNESCO): Walk the Via Jervis — Olivetti's office building (1954-62, Figini-Pollini), the Mensa (workers' cafeteria, BBPR), the Centro Studi (research center, Eduardo Vittoria), and the residential quarter. The ICO building (where the Lettera 22 was designed) is now a cultural hub. Guided tours: Contact the Fondazione Adriano Olivetti (olivettiana.it) for architectural visits. Duomo (11th century): Romanesque — Roman spolia (columns, capitals), a frescoed Romanesque crypt, and a 12th-century bell tower. Castello delle Tre Torri: 14th-century red brick castle — three towers visible from the river. Battaglia delle Arance (Carnival, February/March): Three days of orange battles in the piazzas — teams of aranceri (throwers on foot) vs. teams on carts. Protective gear recommended for spectators in battle zones. Free to watch from safe zones.
