75 years ago, on 9th May 1949, Prince Rainier III became the official sovereign of Monaco. He was 25-years-old. 

To mark this major moment in the history of the Principality, the Palais Princier de Monaco has released an enchanting selection of four precious images from its archives.  

The photographs date from 9th May 1974, when the Principality and the Grimaldi family celebrated the 25th anniversary of Prince Rainier’s rule.


In one, Prince Rainier and his wife, Princess Grace, are photographed with their three children in the Place du Casino. A 16-year-old Prince Albert can be seen on his father’s left side, while Princess Caroline, who was 17-years-old at the time, walks between her mother and her little sister, the nine-year-old Princess Stéphanie.
