The ancient name of this fair was the Fierucola delle lane di San Martino (St Martin's Wool Fair). In the 14th century and the following centuries, in fact, it was on St Martin's Day (11 November) that the large annual wool fair was held.
The fair is dedicated to products derived from sheep, goats, cattle and animals whose breeding does not have the primary or exclusive purpose of meat production: cheeses, local wool with natural dyes, textiles, felt, knitted fabrics, spinning and cheese and butter production tools, shepherds' tools such as sticks, flutes and bagpipes.
