The
foire de Chignat ("fair of Chignat"), former "melons' fair", is one of the oldest fairs in France: its oldest occurrence in documents is from 1303. This event takes place every year at the beginning of September in the field near the Castle of Chignat. In 1195, the lordship of Vertaizon belonged to the troubadour
Pons de Chapteuil, who was eventually attacked by bishop
Robert de Clermont, at war with his brother the count
Guy II d'Auvergne, a close friend of the lord of the city. ==Population==
