Historical Site of the Grimaldis of Monaco - Polignac

The village of Polignac, in the department of Haute-Loire, is the birthplace of Count Pierre de Polignac who married, in 1920, Princess Charlotte Grimaldi, Duchess of Valentinois and daughter of Prince Louis II of Monaco. According to the rules of succession and dynastic substitution established in the 15th century, Pierre de Polignac must renounce his name and his arms, and becomes Prince Pierre of Monaco. From this union were born Princess Antoinette and Prince Rainier, future sovereign of the Principality. The stamp represents the Fortress of Polignac, a site classified as a Historic Monument since 1840.
