Valls will once again become the epicenter of the world of castells. From October 16th to 25th, the Santa Úrsula Fair will fill the city with popular culture, music, heritage, fire, and activities, but it will be on Sunday when all the focus will once again point toward a single place: the Plaça del Blat. There, the Colla Vella dels Xiquets de Valls and the Colla Joves Xiquets de Valls will star in a new battle with the precedent of one of the most extraordinary and tumultuous Santa Úrsula festivals in recent years.
