Sylvie Retailleau explains how she saved the Palais de la Découverte

Sylvie Retailleau, a physicist, former president of Paris-Saclay University, and former Minister of Higher Education, has been president of Universcience since January 2026. In an interview, she explains how the Palais de la Découverte, housed within the Grand Palais, nearly disappeared during the Grand Palais renovation. Intense debates over whether to dedicate the renovated space entirely to classical culture threatened the science museum. Retailleau negotiated a compromise: the Palais de la Découverte ceded one gallery (1,200 m²) to the Grand Palais for about €30 million in revenue over ten years and is lending another gallery (350 m²) until June 2030 for Centre Pompidou exhibitions. In return, Universcience gains full control of the programming for the Palais des Enfants. The Palais de la Découverte is set to reopen in March 2027.

This story matters because it highlights the ongoing tension between classical culture and science in major public institutions, a debate with implications for how cultural and scientific heritage are valued and funded. The resolution—a pragmatic space-sharing and financial compromise—sets a precedent for how state-funded museums can navigate renovation costs and competing priorities. It also underscores the delicate balance of power between institutions like the Grand Palais and Universcience, and the role of government oversight in preserving unique venues that blend art and science.
