On June 18, 1984, in memory of Princess Grace, in Monaco, on the territory of Fontvieille Park, a rose garden was opened, called the Princess Grace Rosary. Prince of Monaco Rainier III thus honored the memory of his wife, who tragically died in a car accident in 1982. Grace Kelly, one of the most beautiful and successful Hollywood actresses, married Prince Rainier III on April 19, 1956, becoming the 10th Princess of Monaco. The trendsetter, the “high-style icon,” adored flowers, especially roses. New varieties of the "Queen of the Flowers" were named after her, the famous French House Meyan, a world leader in selection and cultivation of roses, dedicated a new variety of terry roses with a rich aroma to Princess Grace, calling her Grace de Monaco. In 1981, at the International Rose Exhibition, which opened Princess Grace, an unusual variety was presented with red-cream buds, which, when opened, turned into saturated pink flowers. This rose is called Princess of Monaco. It is not surprising that Prince Rainier III planned the rose garden as a memorial for his beloved wife. In the rose garden of Princess Grace, on an area of 3300 square meters, 4000 rose bushes were planted in more than 150 varieties. But the main flower of the garden is the Princesse de Monaco rose. 30 years after the opening of the rosary, reconstruction and renewal of green spaces were carried out in it. The garden area was increased to 5000 square meters, cozy gazebos were equipped, arches with climbing roses, fountains were installed. The role of "green walls" of the rosary is performed by shorn yews imitating sea waves. To the right of the entrance is a sculpture of Princess Grace, made by the sculptor Kies Verkade. The number of rose bushes in the garden increased significantly, their number increased to 8000. An interesting fact is that roses were not bought for the garden. Prominent nurseries of the world were sent messages about the creation of the Rosary of Princess Grace, and breeders from the USA, France, England, Germany, Denmark, Belgium, Holland and New Zealand sent their best varieties as a gift to the Principality of Monaco.
