This confers a capacity for enchantment and a poetic dimension on the architecture, facilitating the appropriation of spaces and places by people. We wished to re-examine the question of the exhibition space’s boundary as the possibility of a moving and porous border inserted into a hermetic and very constrained envelope.

This decompartmentalization is perhaps in itself one of the means of gradually making the inhabitants aware of the centre’s different cultural practices.
