The big day of the Fiestas de Begoña !!!! The Nights of the Fires is one of the most anticipated of the Great Week of Gijón. In the first minutes of this August 14, weather permitting, the sky of Gijón will be illuminated with the explosion of more than a thousand kilos of gunpowder and thousands of devices that will be launched from the Cerro de Santa Catalina.
