Gorgonzola

Gorgonzola is the town that gave its name to the blue cheese — documented as a cheese-producing centre since AD 879, when the local monks at the Abbey of San Pietro were already aging the surplus summer milk in cool caves and discovering, by accident, the Penicillium roqueforti veining that would become the cheese's signature. By the 11th century 'gorgonzola' was traded across the Po valley; by the 14th the cheese had a documented brand identity; by the 19th it was being exported in industrial quantities to Britain via the new Milan–Treviglio railway. The town today is a 21,092-resident commune in the Milan metropolitan periphery, 24 km east of the Duomo and the eastern terminus of Milan's M2 metro line (32 minutes from Cadorna). Gorgonzola DOP itself is no longer produced inside the comune (the modern DOP zone covers all of Lombardia + Piemonte and is concentrated around Novara/Lecco), but the town remains the symbolic centre, hosts the annual Sagra del Gorgonzola in mid-September with tastings from all 25+ DOP producers across the two regions, and the centro storico has the small Museo del Gorgonzola tracing the cheese's documented history. Beyond cheese: the Naviglio della Martesana runs through the town — the navigable 38-km canal built between 1457 and 1463 by Filippo Maria Visconti to connect the Adda river to Milan, now a Greenways-protected cycling route popular for weekend rides from Milan. The Chiesa Prepositurale dei Santi Gervaso e Protaso (1820 neoclassical) anchors the central piazza; the 11th-c Abbey ruins are at the edge of town. The food is Lombard-northeast: risotto alla milanese (saffron + bone marrow), polenta uncia, ossobuco, the Gorgonzola itself (sweet 'dolce' or aged 'piccante' depending on the producer + cure time), and the local Bonarda red from the nearby Oltrepò Pavese.
