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
