In the nineteenth century, major works were decided to develop a real park: trees and lawns from the old Jardin des Plantes are planted, water tanks are set up, a pond is created, statues of characters famous - Jean Althen, Felix Gras, "Venus Swallows" ... - complete the course.
In the 1960s new tanks are built and their upper parts are terraced: the garden of Rocher des Doms offers a magnificent panorama of the old town, the Rhone and the landscapes to Mont Ventoux.
