At the beginning of the nineties, Barcelona received one and a half million tourists a year. Now there are more than twenty million. Barcelona and its surroundings were at some point the economic engine of Spain thanks to its factories, which attracted millions of inhabitants from the most impoverished provinces via immigration. Today, the industrial sector, although it survives, is not even a shadow of what it once was. Thirty years have passed since the great transforming event in Barcelona, the 1992 Olympic Games.
