Saint Peter's Onion Fair

The Saint Peter's Onion Fair 2025 took place in Isernia around June 28th and 29th, coinciding with the feast of Saints Peter and Paul. As per centuries-old tradition, the streets of the center and Piazzale Erennio Ponzio hosted the stalls of the producers of the Isernia white onion.

Among gastronomic stands, typical products, and onion-based dishes, the fair confirmed its role as an identity event for the Molise capital, capable of uniting the religious, commercial, and gastronomic dimensions.

The 2025 edition re-proposed the traditional structure: stalls of Isernia white onion producers, gastronomic stands, and a market in the historic center and Piazza Erennio Ponzio.
