Grace Kelly & Prince Rainier’s legendary wedding revisited in Monaco Palace exhibition

From 8 June to 15 October 2026, the Prince’s Palace of Monaco will host an exhibition dedicated to the 70th anniversary of the wedding of Prince Rainier III and Grace Kelly.

On 12 April 1956, Grace Kelly, the star of American cinema, arrived in the Principality aboard the liner Constitution. Prince Rainier III welcomed her off the coast of Monaco from his yacht Deo Juvante II, under the spellbound gaze of the entire population. Seven days of festivities followed, until the couple set off on their honeymoon on 19 April.

Seventy years on, the exhibition “The Wedding of the Century”, housed in the Grand Apartments of the Prince’s Palace, will look back at the behind-the-scenes stories, the key figures and the highlights of this event, organised in less than four months following the announcement of the engagement in Philadelphia. The exhibition will feature photographs, moving images, dresses, accessories, gifts and personal documents. Broadcast live on television (one of the first such broadcasts in the history of the small screen) and filmed in colour Cinemascope, the wedding captured the attention of the whole world, blending European monarchical splendour with American-style spectacle.
