The geometrical lines of the carrés de la perspective garden greet visitors upon entering the Jardin des Plantes with marvelous effects of perspective created through careful planning and maintenance. In the 65-acre (26-hectare) botanical garden, bejeweled by flowerbeds, you'll find several attractions, including an alpine garden, a greenhouse split between a tropical winter garden, a Mexican desert ecosystem, and a rose and iris garden. Also visit the small zoo and explore one of the museums on site, which include the Grande Galerie de l'Evolution and the Galerie de Paléontologie. The garden was first created in 1635 by Louis XIII's physician Guy de la Brosse to illustrate plants' medicinal properties to medical students. It opened to the public in 1640.
