Three slithery, 20-metre-high banners shimmer silver and gold outside the stoic 19th-century Bourse de Commerce building, a gentle meander to the Louvre one way, the Pompidou Centre the other. Designed by brothers Ronan and Erwan Bouroullec, the banners bear no signal or logo to suggest that the Bourse is now the Paris home of the private art collection of billionaire François Pinault, founder of the Kering Group and France’s third-richest man.
Instead, this trio of drapeaux reflect the city back to itself: molten gold tones pick up the honey-hued sandstone of Haussmanian buildings; low-lying cloud turns them silver.
