European Heritage Days at the Jardin des Plantes

Four centuries of natural history come to life before your eyes. In 1626, Louis XIII laid the foundations for what would become a global scientific center. To celebrate this fourth anniversary, the institution is unveiling a special program on Saturday, September 19th and Sunday, September 20th, 2026. Curious visitors gain access to spaces usually closed to the public, including the heart of the central library where precious manuscripts lie dormant. Researchers share the daily life of their laboratories, and botanists recount the evolution of these mythical collections. This weekend offers an unprecedented journey through time, allowing you to grasp the importance of this sanctuary of life. A rare opportunity to understand the issues surrounding biodiversity within a heritage that has continued to evolve since the Renaissance.
