Fifty years on, it remains one of the most iconic and glamorous love stories of our time.
On April 19, 1956, the world watched as Prince Rainier of Monaco wed Hollywood actress Grace Kelly at the Cathedral of St Nicholas.
The beautiful bride wore a dress created by Helen Rose, while the groom designed a military uniform especially for the happy occasion.
It was an emotional day for the people of Monaco, who cheered and applauded the newlyweds as they departed the cathedral as husband and wife.
And the principality continued to mark the historic event with several days of celebrations.
Ranier and Grace exchanged vows a day earlier in a civil ceremony held in the throne room at the Palace of Monaco, attended by their close friends and family.
