Fujiko Nakaya fills Bourse de Commerce with Fog Sculpture

Fujiko Nakaya’s Cloud #07156 transforms the Rotunda of the Bourse de Commerce in Paris into a fog sculpture from June 4, as part of the exhibition Clair-obscur. Created by the Japanese artist, the work fills Tadao Ando’s circular interior with a dense white cloud made of water vapour, placing visitors inside a shifting environment where bodies, architecture and visibility constantly change.

Cloud #07156 by Fujiko Nakaya transforms the Bourse de Commerce Rotunda

Nakaya, born in Japan in 1933, has worked with fog as an artistic material since the late 1960s. After leaving painting, she began developing large-scale atmospheric works outside the traditional limits of the studio. In 1969, in collaboration with engineer Thomas Mee, she created a system capable of producing a cloud sculpture from water fog. This process excludes chemical effects, relying instead on high-pressure pumps and rows of nozzles that emit microdroplets similar to those found in natural mist.

Cloud #07156 continues Nakaya’s long investigation into unstable and temporary forms. The sculpture is natural in its composition, but technically produced; it appears, thickens, disperses and reforms according to air currents, temperature, humidity and the movement of visitors. The work cannot be seen from a fixed viewpoint. It must be entered, crossed and felt as a changing condition, where perception depends on distance, density and the body’s position within the cloud.

At the Bourse de Commerce, the fog encounters one of Paris’s most distinctive museum interiors. The Rotunda combines the historic circular architecture of the building, its panoramic mounted canvas and the concrete cylinder designed by Tadao Ando. Nakaya’s intervention alters the reading of this space by interrupting sightlines and softening architectural boundaries. What is usually open to observation becomes temporarily opaque. Visitors appear and disappear inside the white atmosphere, while the building itself seems to lose its stable outline.

The work also creates a different relationship between public and artwork. In the morning programme Brume(s) matinale(s), held outside regular opening hours, visitors are invited to experience Cloud #07156 through a guided sensory encounter. Museum guides lead a gradual immersion involving contemplation, collective movement, attention to mist, and observation of the sky. Sight, touch and hearing become part of the visit, as the body registers changes in light, temperature and spatial depth.

For Nakaya, fog is never only an image of nature. It is a material that resists permanence and control, making visibility uncertain and time perceptible. Inside the Rotunda, this quality becomes especially precise: the cloud can open a view, block it, or replace the museum’s panoramic perspective with a temporary state of disorientation. The question is no longer where to stand in order to see the work, but how to experience a space when seeing becomes partial.
