Between the 12th and 13th centuries, the areas surrounding the parish of Gorgonzola witnessed a rapid and widespread spread of the new religious order of the Humiliati. They engaged in community prayer, commercial and artisanal activities, particularly woolen cloth weaving, and, thanks to their financial resources, lending, economic assistance, and tax collection. In the first half of the 13th century, the Humiliati settled in Gorgonzola in the Corte dei Chiosi, building an oratory that would later evolve into the small church of San Pietro. Of the convent, only the terracotta and river stone façade remains, with a portico of four pointed arches on pillars, a stone pier, and two pointed windows entering the courtyard at number 12 of what is now Via Piave. The interior, which has lost the slab dividing the two floors, still features the original roof trusses. On the left, another building arranged perpendicularly denotes a 16th-century expansion of the convent: it features a portico with round brick arches, now unfortunately walled up. The order of the Humiliati was suppressed on July 23, 1568, by order of Pope Pius V, and since then the convent has undergone various transformations, ultimately resulting in its current state. However, it is still privately owned. As a reminder of the presence of the Humiliati, the Sant'Erasmo Fair existed until 1800, which served to market the linen produced in our area following the production and marketing of yarn, a function of the Humiliati.
