New details: Grace Kelly's wedding to Prince Rainier

To mark 60 years since the fairytale wedding of Grace Kelly and Prince Rainier of Monaco III, the palace has released previously unseen images from their archives. Not only that, but the couple’s son has given a rare personal insight into what went on behind the scenes of one of the most iconic weddings in history.

"It was such an incredible affair, and it's left such a mark on people," Prince Albert II says in a new interview with People. "For us…it was our parents getting married. But what it's meant for Monaco, for people around the world, and, how their story continues to fascinate people, that's something unimaginable. Those who attended who are still with us still talk about it."

The elaborate religious wedding ceremony that took place on April 19, 1956 at the Cathédrale de Monaco has gone down as one of the most famous weddings of the 20th century that was watched live by over 30million people and covered by 1,500 reporters from around the globe.

By far the most memorable and iconic aspect of the wedding was the new Princess’ wedding gown, designed by the head costume designer of MGM Studios, Helen Rose. 36 seamstresses worked for six weeks to craft the gown which was made of Brussels rose point lace over a century old, silk faille and taffeta and was adorned by thousands of hand-sewn seed pearls."

Described as “an incredible affair” that “left such a mark on people” by Monaco’s Prince Albert II, today marks the sixtieth anniversary of the marriage of Prince Rainier III of Monaco and Hollywood actress Grace Kelly.
