Located at the crossroads of the rocky plateau and the Bretonnier Valley in Nantes, the Jardin de la Beaujoire was established in 1971, 6 km from the city centre, with an area of about 14 hectares, offering beautiful views of the River Erder, the rose garden being the main attraction. Combining perennial plants and nearly 20,000 rose bushes, the garden also houses the National Reference Collection of the magnolia plant.
