From June 4 to September 14, 2026, the rotunda designed by Tadao Ando for the Bourse de Commerce – Pinault Collection will host an installation by Japanese artist Fujiko Nakaya, a “fog sculpture” titled Cloud #07156.
Created specifically for the exhibition “Clair-obscur,” the work introduces into the museum space an intangible presence—a cloud of water vapor that continuously redefines the boundaries of the architecture, undermining its visibility through “ephemeral and partial transparencies”. A pioneer of these “fog sculptures” since the 1970s, Nakaya developed, together with engineer Thomas Mee, a complex high-pressure pump misting system to generate constantly shifting environments—that is, unstable and immaterial perceptual devices that invite the public to experience the work as a passage rather than as mere self-contained contemplation.
In dialogue with the rotunda—an open, circular, and vertiginous space—the fog subtracts visibility, acting as an “antipanopticon,” as Anne-Marie Duguet explains, challenging the very notion of a fixed point of view and instead reaffirming the centrality of a total, embodied experience.
