In the heart of Isernia, an ancient city rich with memories of distant times, every year a festival is renewed that smells of tradition and earth: the Onion Fair.. This event, one of Molise’s most characteristic, celebrates a simple yet extraordinary product—the onion—which for centuries has represented the lifeblood and identity of the land and its people.
The roots of this fair stretch back to the Middle Ages, with documents dating to 1254, granted by Count Ruggero of Celano, which guaranteed tax exemptions for participants. Over the centuries, the tradition evolved and intertwined with religious and popular customs linked to the feast of Saints Peter and Paul, which marks the Molise calendar.
Luigi Vittorio Bertarelli described the fair in 1926 as a market where farmers from Isernia and nearby areas brought onions of all kinds, notably the large, wine-red “San Pietro red” onion—a symbol of this generous land. It is not only a commercial moment but a festival of flavors and conviviality that still fills the streets with music, dances, and traditional onion-based dishes.
A legend connects the onion to Saint Peter: his mother, a greedy and unkind woman, was condemned to hell for her lack of charity, saved only thanks to a single act of kindness toward a poor hungry woman to whom she gave an onion. Moved with pity, Saint Peter tried to pull her from the flames with a braid of onions, but his mother, selfish as she was, tried to save herself alone, breaking the cord and condemning herself forever. This story, full of symbols and lessons, has always accompanied the fair, reminding all of the importance of generosity and community. Participating in the Isernia Onion Fair means immersing yourself in an experience that blends history, culture, and flavors, where every onion tells a piece of authentic, living Molise.
