The itinerary opposes radical contemporary architecture with the living industrial heritage of the “Catalan Manchester”, paradigm of the industrial textile revolution of Barcelona, ferment of a new sociology: the Catalan bourgeoisie. Radiant technological corporative glazed architecture live together with brick old factories, now converted into potent museums and universities in the 22@ District, dedicated to knowledge, innovation and new technologies activities. The Forum area, symbolical ending of the paradigmatic Diagonal Avenue that leads into the sea, concludes the route of a new Barcelona.
