HONEYMOON

Best bet: Botswana.

The couple has described a 2016 five-day safari trip to the African nation as the time when they really got to know each other. Another return trip would re-create the time when they first fell in love: camping in the African wilderness, sleeping under the stars.

The marriage of Academy Award–winning American actress Grace Kelly and Monaco’s Prince Rainier III set the template for all future royal weddings. Grace was truly America’s first princess.

Famous for her roles in Rear Window, Dial M for Murder and The

Country Girl, she was 26 when she retired from movies to marry Rainier, 32, and take the title of Princess of Monaco.

The world’s media flocked to Monaco for the lavish two-day event: 1,800 reporters and photographers were waiting at the port when Grace sailed in on the ocean liner the S.S. Constitution with 80 pieces of luggage and her poodle, Oliver.

The week leading up to their wedding was a whirlwind of balls, firework displays and garden parties. On April 18, 1956, the pair married in a short civil ceremony in the Palace Throne Room of Monaco.

The Dress: The iconic Helen Rose–designed dress (said to have inspired Kate Middleton’s gown) was a masterpiece of silk taffeta and antique lace with a fitted bodice, long sleeves and billowing skirt that took 30 seamstresses three weeks to make.
