Queen Elizabeth II, Prince Philip Celebrate 70th Anniversary with Special Announcement

Staying married for nearly seven decades is definitely worth celebrating, and the British royal family knows exactly what to do to commemorate this anniversary.

When they met as teenagers—Elizabeth was 13 and Philip was 18—the future queen confessed to falling in love with him immediately. However, their romance was sparked when she and her family visited the Royal Naval College and he gave them the tour.

After he returned from serving in World War II, they announced their engagement.

On November 20th, 1947, Queen Elizabeth—then Princess Elizabeth—married Lieutenant Philip Mountbatten at Westminster Abbey in a lavish wedding, attended by nearly 2,000 people.

To commemorate their incredible 70 years of marriage, the Royal Mail is releasing four commemorative stamps, showing moments from the couple’s time together.

On top of that, the royals—now 91 and 96—had an official photo taken to celebrate the occasion.
