The discovery of the gardens is organized around three major themes: botany and more specifically ethnobotany, that is to say the plants used in the Ban de la Roche in the eighteenth century (medicinal, aromatic, culinary, tinctorial plants, etc.). The manner of presentation of this garden is inspired by the boxes of the cabinet of curiosity of J.F. Oberlin. Pedagogy and teaching to children in connection with the discovery of the plant world, are associated with the creation of a pedagogical vegetable garden, a real extension of the Children’s House. Mapping and observation of the elements are offered in the Pasteur’s pleasure garden. The theme of the observation of planets and the dissemination of knowledge through cartography is developed through casts of objects existing in the museum’s collections. An orchard and a meadow complete these three gardens.
