Classified as historic monuments, the terraced gardens of the Dauphinois museum, located in the former Sainte-Marie-d’en-Haut convent in Grenoble, have been completely redesigned and redeveloped by landscapers from the Sinequanon’ design office. Started in January 2023, the work carried out by Cheval Restauration Patrimoine included the revegetation of the site, its accessibility for disabled people, the lighting of the paths, the highlighting of certain significant elements… The steep slope separating the highest terrace from the lowest required helicopter hoisting operations. The cost of this development, financed by the department, amounted to €1.2 million including tax.
