Emergency services for Castilla y León said it had received several calls about the collapse of the fountain. Part of the structure gave way after several people climbed on it to celebrate Spain’s win, local media reported.
The emergency service said it had notified the city’s local police, as well as Salamanca’s Civil Guard, its fire brigade and the local emergency medical service – which dispatched a mobile intensive care unit and a basic life support ambulance to the scene.
The emergency medical service later requested the presence of the Civil Guard at the local health centre to investigate the death of the boy who was treated there, the Castilla y León’s regional government’s website said.
It also requested the Civil Guard activate psychological support for the family.
The city’s council said it “hopes for a speedy recovery of the others who have been affected by the incident”.
Spain beat Argentina 1-0 in the World Cup final on Sunday after Ferran Torres scored in extra time.
It is the country’s second ever World Cup win, after their last victory in 2010.
Earlier this month, three people died from suffocation during World Cup celebrations in Mexico City, while a 30-year-old man also died in an epileptic crisis.
