They are located at 5, Chemin de la Prelle, Ban-de-Sapt, Vosges, Grand Est, France, and open daily in the warmer months; an admission fee is charged.
The gardens opened to the public in 1996 after 7 years of design and planting under the direction of landscaper Jacques Couturieux.
They form part of the rehabilitation of a former quarry, and traces of the pink sandstone and trench warfare from World War I still remain.
Today the gardens comprise ten distinct areas linked by sweeping lawns and walkways.
The garden also contains tree peonies, phlox, saxifrage, water plants, and various perennials and shrubs.
