Prince Albert and his bride topped off a splendid religious ceremony with an even more lavish reception.
The centrepiece of the banquet was a towering wedding cake, made of 50 kilos of strawberries and 2,000 edible blossoms including Proteas, South Africa's national flower in honour of Charlene.

In keeping with their wish to respect the environment, many of the ingredients had been freshly picked from Roc Agel, the estate that Rainier III gave to Princess Grace as a wedding present in 1956.
After this lavish fare, the night sky lit up with a spectacular fireworks display, featuring a giant bouquet of 'fire flowers'.
Hymne a l'amour, originally by Edith Piaf was sung a capella, and the foghorns of the yachts sounded their approval throughout the bay.
Then, watched by 450 VIPs, dignitaries and European royals, the couple closed their unforgettable three-day celebration with their first dance as man and wife.
