Prince Harry and Meghan Markle’s royal wedding on April 1, 2018, captivated the world.

An estimated 1.9 billion people tuned in to watch the pair say their “I dos,” making it one of the biggest televised events in history. A wedding ceremony of such scale required a great deal of careful planning and hard work from everyone involved, from the wedding cake baker, Claire Ptak, who spent five days perfecting the couple’s lemon sponge confection with her team, to the dressmakers, who worked for “hundreds of hours” sewing fabric and washing their hands every 30 minutes to keep the veil immaculate.

“A great level of detail went into the planning of our wedding day,” Meghan acknowledged in an audio clip from the couple’s “A Royal Wedding: The Duke and Duchess of Sussex” exhibit in Windsor. “We knew how large the scale of the event would be, so in making choices that were really personal and meaningful, it could make the whole experience feel intimate.”

It was a fitting goal for the couple, who also got engaged in an über-intimate manner. ​​”It was a cozy night,” Meghan told the BBC. “We were roasting chicken. It was just an amazing surprise. It was so sweet and natural and very romantic. He got down on one knee.”

Harry and Meghan were introduced by a mutual friend in 2016 and became betrothed just one year later. “The fact that I fell in love with Meghan so incredibly quickly was a confirmation to me that all the stars were aligned. Everything was just perfect,” Harry said in the couple’s engagement interview.

Though the pair’s big day was highly publicized and televised for the world to see, there were some details that the public didn’t learn until much later — including the fact that Harry and Meghan secretly exchanged vows in a backyard ceremony three days before their wedding, as they told Oprah Winfrey. In their Netflix docuseries Harry & Meghan, the couple shared several more special moments from their nuptials, offering viewers an intimate peek at their first dance as well as Meghan’s mindset on the big day.

“On the day of our wedding, it’s like I went into a really calm space. I don’t know how I was so calm,” Meghan said. “I look back at that: How was I so calm? And all I wanted was a mimosa, a croissant. And to play the song ‘Going to the Chapel.’ Oh, that’s what I did. And it was great.”

In the series, Harry also spoke about the expectation for the couple to have a big wedding. “There was an expectation, right? Diana’s boy It was an expectation to have a public wedding,” he said. “It was like, ‘Mission complete with William. Now let’s see if this goes the distance with Harry and then we can actually go, “Job done”.’ ”
