European Heritage Days 2026: Discover Paris's Art Deco buildings and treasures

In France, theArt Deco craze didn't last long: it began in the 1910s, reached its peak in 1925, and gradually died out in the 1930s. And yet, even today, this artistic movement is highly appreciated. Traces of it can still be found in Paris: buildings, decorative elements, glass roofs, frescoes... These treasures of the past can be hidden or in plain sight.

Some of the capital's Art Deco buildings are well known: the Samaritaine, the Molitor swimming pool, the Musée des Arts Décoratifs... Others are more discreet, and some may even surprise you.

If you’re a fan of this architectural and artistic style, seize the opportunity of the Heritage Days to tour the Art Deco remnants that dot Paris. During the weekend of September 19–20, 2026, a host of cultural sites will offer themed tours and reveal all the secrets of their history and architecture. It’s the moment to soak up knowledge and become an expert on Paris and its surroundings!
