The Ferias are the traditional popular festivals which are organised in the cities of Gascony throughout the summer. Based on a Spanish tradition, they include races of Landes bulls or cows. During almost one week the streets are dominated by celebrations, during the day and during the night. The most famous Ferias of the region are those of Bayonne, Mont de Marsan and Dax. As legendary features of the region they have been part of the inventory of the intangible cultural heritage of France since 2010.
