Drawing on the Salins du Midi, a historic salt extraction plant obtained from underground springs, Henna Burney and Kalijn Sibbel, material designers at Atelier Luma, developed the "Wall of Salt" project, consisting of over 4,000 square Camargue salt-based panels, which cover the walls of the elevator lobbies of nine of the twelve floors of the LUMA Arles Tower campus designed by Frank Gehry.
