The couple were forced to cancel their original nuptials amid the coronavirus pandemic.
Beatrice and Edoardo had been due to marry on 29 May 2020 at the Chapel Royal at St James's Palace in London, with a reception to take place at Buckingham Palace after the ceremony.
When lockdown restrictions began to lift in the UK, the Princess made a last-minute decision to organise a wedding at the Royal Chapel of All Saints at Royal Lodge in Windsor, close to where she had grown up.
The private ceremony was attended by the couple's closest family members, including the Queen and the Duke of Edinburgh, who had been staying at Windsor Castle throughout lockdown.

Her wedding venue wasn't the only last-minute change for Beatrice.
Originally, she wasn't meant to borrow a dress from the Queen, but after a change of heart about her bridal gown, Beatrice "made a request [to loan one from the Queen], and that was kindly granted – and it looked amazing," a friend of the bride and groom told PEOPLE.
The pal added: "It was touching for both of them."
Beatrice wore one of Her Majesty's vintage Norman Hartnell dresses from the 1960s on her big day, which was remodelled and fitted by the Queen's dresser Angela Kelly and dressmaker Stewart Parvin.
The gown was made from Peau De Soie taffeta in shades of ivory, trimmed with ivory Duchess satin, with organza sleeves. It was encrusted with diamanté details and a geometric checkered bodice.

Meghan was escorted to St George's Chapel in Windsor by her mother Doria Ragland in the car and she walked down the first half of the aisle on her own. Charles then accompanied his daughter-in-law to the altar for the second half.
Harry later spoke about the moment in the BBC One documentary Prince, Son and Heir: Charles at 70, saying: "I asked him to and I think he knew it was coming and he immediately said, 'Yes, of course, I’ll do whatever Meghan needs and I’m here to support you'. For him that's a fantastic opportunity to step up and be that support, and you know he's our father so of course he's gonna be there for us."
Princess Eugenie and Jack Brooksbank spent months planning their royal wedding in October 2018, but they had to leave one decision until the morning of their big day, and for good reason too.
Due to the unreliable British weather in October, Eugenie and Jack only settled on what carriage they would ride on Friday morning, just hours before saying their vows.
The bride and groom looked like a real-life fairytale couple as they rode in the Scottish State Coach. They chose the coach, which is covered but has large glass windows, in case it rained. While the newlyweds were spared of any showers, it was a very windy day in Windsor.
Princess Diana made changes to her wedding vows when she married Prince Charles in July 1981. She was the first royal bride to omit the word "obey" from her vows, something which Kate Middleton, Meghan Markle and Princess Eugenie also followed.
The Duke of Edinburgh's attendance at his grandchildren Prince Harry and Princess Eugenie's weddings, in May and October 2018 respectively, wasn't confirmed until last-minute.
Prince Philip had undergone hip surgery the month before Harry and Meghan's nuptials and Buckingham Palace only confirmed that the Duke would be present the day before.
Similarly, the Duke's name was not listed alongside the Queen's on the Order of Service at Eugenie's wedding, but he delighted royal fans with his attendance on the day.
Prince Charles and Camilla's wedding in 2005 was postponed by a day so that the Prince of Wales could attend Pope John Paul II's funeral in Vatican City.
The royal couple's dedication and civil service took place in Windsor on 9 April instead.
The Swedish royal's attendance at the ceremony was seemingly last-minute and she gave birth to son Prince Nicolas two days later.
Madeleine revealed during an interview with Swedish magazine Mama that she was having contractions all day at the royal wedding.
