During the 1950s, the Valencia ground experienced the deepest change in its whole history. That project resulted in a stadium with a capacity of 45,500 spectators, that eventually saw destruction by a flood in October 1957 that arose from the overflowing of the Turia River. Nevertheless, the Mestalla not only returned to normality, but also some more improvements were added, like artificial light, which was inaugurated during the 1959 Fallas festivities.
