Starting from the rubble of its original building, Porte B. reappropriated its materials and walls to develop a new type of space. Open-plan and modular, it adapts and transforms over the course of the interventions. It is a platform in perpetual mutation, a creative space permeable to the world. For its inaugural exhibition, Porte B. symbolically chose to extend its playground beyond the gallery walls and to question its immediate environment: the city. Entitled No Man's Land, this exhibition, which brings together seven young French and European artists, thus seeks to put our relationship with urban space into perspective. Sometimes poetic and playful like the unusual combinations of Victor Cord'homme, the digital collages of Raphaël Guez or the fragmentary installations of Jeanne Varaldi and Vasco Mourão, sometimes intimate and disturbing with the epidermal walls of Amélie Bernard, the visions of dehumanized habitats of Vincent Marcq or the vestiges of signs of Prosper Legault, these different appropriations of urban space enrich our imagination to allow us to rethink the city and to inhabit it differently.
