Prince Albert II, for his part, embodied the most affectionate moments of the celebration, sharing constant kisses and tender gestures with both his wife and their two children, a sight we're not often witnessing. At the same time, he immersed himself in the crowd, greeting his fellow citizens with handshakes as he made his way to the palace gates. Many of them left congratulatory messages for his two decades on the throne, some of which were shared on the official social media accounts of the Princely House.

The event began in the early evening around six thirty and carried on into the night until about ten thirty, taking place in the Place du Palais. The Monegasque anthem was sung, a traditional folklore show was performed, and Rainier III’s successor gave a heartfelt speech. To wrap up the celebration, everyone enjoyed a giant cake under a colorful light display that, as expected, was a big hit with the little royals.
