“An existing space may outlive its original purpose and the raison d’etre which determines its forms, functions, and structures; it may thus in a sense become vacant, and susceptible of being diverted, reappropriated and put to a use quite different from its initial one. A recent and well-known case of this was the reappropriation of the Halles Centrales, Paris’s former wholesale produce market, in 1969-71. For a brief period, the urban centre, designed to facilitate the distribution of food, was transformed into a gathering-place and a scene of permanent festival — in short, into a centre of play rather than of work — for the youth of Paris.”
