The young royal and her brothers Andrea and Pierre moved to the region after Stefano's death.
Royal guests included the bride's uncle Monaco's Prince Albert II, her mother Princess Caroline of Hanover and her half-sister Princess Alexandra of Hanover.
Charlotte's five-year-old son Raphael, from a previous relationship with comedian Gad Elmaleh, and Dimitri's seven-year-old daughter Darya, from his first marriage, were also in attendance, along with Dimitri's model mother Carole Bouquet
The religious part of the royal wedding was captured by photographer Félix Dol-Maillot, who showcased Charlotte's stunning gown by Italian designer Giambattista Valli to perfection.
Charlotte and Dimitri officially wed in a civil ceremony at Monaco's Prince's Palace on June 1.
The famously fashionable brunette beauty wore a grey, brocade Saint Laurent mini-dress embellished with large bows for the first part of the day, before shunning a traditional wedding dress in favour of an exquisite Chanel jumpsuit for a private reception at Monaco's Villa la Vigie, Harper's Bazaar Australia reports.
Charlotte - who is 11th in line to the throne of the tiny European state - was the picture of her actress grandmother Grace Kelly in a vintage, sleek hairstyle and old Hollywood makeup finished with a red lip.
Charlotte finished her Chanel wedding look with a special tribute to the late Princess Grace by wearing a 64 carat Cartier diamond necklace from Kelly's personal collection.
The elegant piece was gifted to the star by her husband Prince Rainier III of Monaco on their own wedding day in 1956.
The Monagesque royal wedding is the latest in a long line of celebrity marriages, after Prince Harry and Meghan Markle, Princess Eugenie of York and her longtime love Jack Brooksbank, Lady Gabriella Windsor and Thomas Kingston.
Game of Thrones' Sophie Turner and Joe Jonas also wed in an opulent second ceremony in Provence over the weekend, while Big Little Lies' Zoe Kravitz also held her nuptials with actor fiancé Karl Glusman in Paris on Saturday.
Congratulations Charlotte Casiraghi and Dimitri Rassam!
