A small square named after the Prince of Monaco (Place Prince Rainier III De Monaco) appeared in Le Baux for a reason. The fact is that in 1642, under an alliance agreement with Grimaldi from Monaco, these rulers were granted the title of Marquis de Bo. Since then, it has been used by the heir to the Monegasque throne. The square is named after Prince Rainier, in gratitude for his contribution to the development of the village. Today, the area is actively used for various exhibitions and open-air vernissages.→
