The grain silo in the town of Louvres is a striking architectural structure. It is an involuntary monument that is no longer in use. It is a space of paradox, in the centre of the city, but at a remove from the inhabitants. It is attractive for its grandeur and its aesthetics, but repulsive for its massiveness and its disturbing silence. The project reverses the perception of the silo via two interventions, by exploiting its partially hollowed-out architectural structure for an unusual vertical urban walkway and by creating a seed-bed for associative micro-activities in the second part of the building that includes, among other things, a cooperative restaurant. The architecture has thus been popularised and made less monumental through these new uses.
