The exhibition 'Architectures without Place (1968-2008)' presents a series of works that either were never built or no longer exist: a vast field which ranges from theoretical speculations, visionary prefigurings and ideas competitions to modified projects, ephemeral installations and botched buildings. This variegated realm of the unbuilt (or of the now non-existent) allows us to analyse the conceptual heritage of a long period of Catalonian cultural history; in other words, it lets us dissect forty years of architecture produced locally, highlighting the prevailing ideas at each step of the way. This is a heterogeneous field of project design in which converge other disciplines fuelled by a powerful desire to articulate and transform space: comics, theatre, film, ephemeral installations and the visual arts in general.
