The opening date for the new Fondation Cartier extension design from Jean Nouvel has been announced as October 25th, 2025. The new space, which will take over a Haussmann-era building directly across from the Louvre on the Rue de Rivoli, is about 91,000 square feet (8,500 square meters). The project marks the 40th anniversary of the foundation's establishment, which preceded Nouvel’s original 1994 design, and offers a resolution to a previous plan for the Île Seguin that was dissolved in 2014.  (You can check out some new interior shots of the extension below, courtesy of the Foundation photographer Martin Argyroglo.)
