The Petit Palais welcomes Loris Gréaud's exhibition "Les Nuits Corticales", the artist's most ambitious exhibition in France since his dual project at the Louvre and Centre Pompidou in 2013. Enigmatic, delicate, sometimes disquieting or even immaterial, Loris Gréaud's proposal will haunt the museum, which, like a ghost ship, will be traversed by rumors, opaque systems and singular encounters. The exhibition will permeate the Petit Palais, transforming it into a veritable sounding board(s), until it becomes the pulsating heart of our world
