The Fête de la Science 2026 returns from 2 to 12 October with free programming that invites the general public to discover science from a concrete, accessible perspective. For ten days, researchers, associations, cultural institutions and local authorities offer workshops, talks, tours and experiments to show how research shines a light on our daily lives. This 35th edition, under the theme "Saveurs savantes", explores the links between food, taste, health and the environment. In Louveciennes, in the Yvelines (78), the event has long been driven by the association Louv'Science, which participates each year in the Fête de la Science with the support of the town hall and organizes conferences, exhibitions and workshops around the national theme.
Situated between the Seine, Marly-le-Roi and Versailles, Louveciennes underwent a turning point during the reign of Louis XIV. The construction of the Marly Machine and the Louveciennes aqueduct, designed to feed water to the gardens of Versailles and the Marly palace, profoundly shaped the town’s landscape and history. In the 19th century, the hillsides, lanes and the banks of the Seine attracted numerous Impressionist painters, among them Camille Pissarro, Alfred Sisley, Pierre-Auguste Renoir, and Élisabeth Vigée Le Brun, who drew inspiration from its scenery. Today, Louveciennes preserves this remarkable heritage, harmonizing historic residences, the aqueduct, natural spaces and the artistic legacy.
In Louveciennes, science resonates in a setting where heritage, nature, and culture continually echo one another. The Science Festival offers a way to explore a range of topics through accessible formats, giving the public a chance to chat with enthusiasts and gain a clearer view of today’s major scientific challenges. The events hosted in the town naturally complement a visit to its iconic sites, from the ancient aqueduct to the landscapes immortalized by the impressionists, to the town center. This blend of local history and scientific culture makes Louveciennes an appealing destination for those who want to learn while discovering the territory in a new light.
Conference: Food, Climate, and Nutrition
The topic of food and nutrition may seem trivial, yet it sits at the heart of global economic and social tensions. More than a billion people still suffer from malnutrition. Meanwhile, rising obesity and diabetes show that a portion of the population lacks access to healthy diets. Environmental pressures are also mounting, with climate change threatening crops, widespread pesticide use impacting biodiversity and our health. Food thus stands at the crossroads of all these issues. Louis-Georges Soler, research director at INRAE and a speaker at IDDRI’s Think Tank, will address these challenges during this conference to map out the links and interdependencies and open the discussion on viable levers of action.
