The Botanical Garden of Palermo is located next to Villa Giulia, bordering the Kalsa district. In 1779, to accompany the newly founded Accademia di Regi studi, which had annexed the chair of Botany and Medical Matters, a small botanical garden was created, adjacent to the Porta di Carini, but became insufficient for the needs of the chair, in 1786 it was transferred to its present location.
Between 1789 and 1795 the main buildings were built, the Gymnasium and the two lateral bodies of the Tepidarium and the Calidarium, in neoclassical style, designed by the French architect Leon Dufurny.
Originally the garden, enriched with pools and fountains and a magnificent Aquarium, was divided into rectangular plots to divide the collections according to Linnaeus' system, but in the early nineteenth century it was modified. The Garden was still enlarged in later periods, and a grove of exotic plants and the Winter Garden, for example, was created in a large greenhouse. In the 1930s it acquired its definitive appearance, with the entrance area divided into regular areas and the southern area furrowed by more articulated paths.
