In the future Ch\u00e2tillon\u2013Montrouge station of the Grand Paris Express, artist Laurent Grasso envisions a vast celestial vault inspired by Renaissance painted skies. Titled Ciel d&#8217;argent, the work envelops travelers from the moment they enter the station. Conceived in close dialogue with the architecture designed by David Trottin, the composition originates in the artist&#8217;s studio before being digitized and screen-printed onto 2,750 metal slats. Once assembled, they will form nearly 800 m\u00b2 of ceiling, suspended above the flows, staircases, and daily movements.    <\/p>\n<p>M\u00e9talobil operates at the heart of this installation, ensuring the fabrication, execution, and installation of the work. Aluminum, the project&#8217;s central material, is folded according to an irregular pattern that captures light and extends the sky across the station walls. Installation, carried out using monumental scaffolding between level -4 and the ceiling, will continue until the supply shaft is closed. This project is part of a broader endeavor: the artistic program of the Grand Paris Express, for which M\u00e9talobil supports the realization of over thirty works at the intersection of art, engineering, and public space.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][divider line_type=&#8221;No Line&#8221;
