Fiera delle Cipolle di San Pietro
The historic fair of Isernia documented since 1487
About Fiera delle Cipolle Isernia
A fair that spans the centuries
The Fiera delle Cipolle of Isernia, also known as Fiera di San Pietro, is one of the oldest mercantile traditions in Molise. The festival dedicated to the apostle Peter has been documented since the 15th century: as early as 1487 the 'Capitoli della Bagliva' mention 'the feast and fair of St. Peter the Apostle', while subsequent chapters (1539-1620) regulated the sale of onions, cited as a characteristic product of the Isernia plain.
The white onion of Isernia
The heart of the fair is the white Isernia onion, with its sweet flavor and flattened bulb, an agricultural symbol of the territory. The streets of the center fill with local producers, while restaurants and stands offer dishes and omelets made entirely from onions, transforming the city into a large taste laboratory. A popular legend links the onion to Saint Peter, whose mother, according to the story, gave a single onion to a poor old woman.
Between faith and market
Traditionally held around June 28th and 29th, coinciding with the feast of Saints Peter and Paul, the fair takes place in Piazzale Erennio Ponzio and the historic center, intertwining the religious dimension with the commercial and gastronomic one. It is an identity event that for centuries has drawn visitors and producers from the entire province to Isernia, the capital of Molise.
