On Friday, the Palais Princier de Monaco announced the opening of the exhibition Le mariage du siècle: Monaco. 12–19 Avril 1956, to be presented in the Grands Appartements of the Palais Princier de Monaco from June 8th to October 15th, 2026.

The exhibition is being held on the occasion of the 70th anniversary of the marriage of Prince Rainier III of Monaco and Miss Grace Kelly, which took place in April 1956, three months after the announcement of their engagement in Philadelphia, Pennsylvania.

Bringing together photographs, film material, garments, accessories, gifts, and archival documents, the exhibition examines the sequence of events surrounding the wedding, from the arrival of Miss Grace Kelly to the Principality of Monaco on April 12th, 1956, to the couple’s departure for their honeymoon on April 19th, 1956, situating the ceremonies within the broader context of their international reception.
