The rapid economic expansion reinvigorated old industrial areas: the Basque Country and Ferrol northern coast (iron and steel, shipbuilding), in and around Barcelona (machinery, textiles, cars and petrochemicals) it also drove an enormous expansion in refining, petrochemicals, chemicals and engineering. To help achieve rapid development, there was massive government investment through key state owned companies like the national industrial conglomerate Instituto Nacional de Industria, the mass market car company SEAT in Barcelona, the big steel plant of Ensidesa in Avilés and the shipbuilder Empresa Nacional Bazán. With heavy protection from foreign competition within the domestic Spanish market, these companies led the industrialisation of the country, restoring the prosperity of industrial areas like Barcelona and Bilbao and creating new industrial areas, most notably around Madrid.
