Thousands of people have gathered at royal landmarks across the UK to mourn the death of the Queen, who passed away peacefully at Balmoral on Thursday afternoon. Her grandchildren, Prince William and Prince Harry, joined their respective wives Kate and Meghan, in a surprise visit to Windsor Castle on Saturday where they spoke to grieving well-wishers and looked at tributes for the late Monarch.
The Queen famously showed unrelenting support for the Sussexes and the Prince and Princess of Wales, sharing wisdom with the couples throughout their royal careers. One occasion that Prince William sought help from his grandmother was during the preparations for his wedding to university sweetheart Kate Middleton.

The late Monarch told the Prince of Wales to scrap the lengthy list in favour of a more intimate affair which prioritised William and Kate's closest friends and family.
Owing to his status as future king, William and Kate's wedding in 2011 was a monumental event, but the heir to the throne was 'very unhappy' when he received the extensive official wedding guestlist which included 777 names.
While consulting on the wedding plans, the now-Prince of Wales complained to the Queen that he was 'horrified' at the strangers on the guestlist - but she told him to rip up the list and start again.
Speaking in a 2011 book Our Queen written by Robert Hardman, Prince William said: "I came into the first wedding meeting, post-engagement.
"And I was given this official list of 777 names, dignitaries, governors, all sorts of people, and not one person I knew.
"They said: 'These are the people we should invite'. I looked at it in absolute horror and said: 'I think we should start again'."
William revealed how he then approached the late Queen for help with the wedding dilemma. He said: "I rang her up the next day and said: 'Do we need to be doing this?'
"And she said: 'No. Start with your friends first and then go from there'. And she told me to bin the list.
Praising her advice, Prince William continued: "She told me there are certain times when you have to strike the right balance. And it's advice like that, which is really key, when you know that she's seen and done it before".
Ditching the official guestlist, the Prince and Princess of Wales filled Westminster Abbey with their friends and family, as well as old colleagues and school pals who had supported them throughout the years.
Princess Kate even invited John Haley, the landlord of The Old Boot Inn in her hometown, and the Middleton family's local haunt.
Speaking on the BBC's documentary Royal Wedding: A Day to Remember, John said: "It was great that Kate and William were allowed to invite all their own friends.
"Friends from the village, from uni, friends that she grew up with. She invited me, I've known her 15 years or so. It was fabulous".
Other more high-profile guests included Sir Elton John, David and Victoria Beckham, Joss Stone and Rowan Atkinson.
The Queen's close relationship with William and Harry was well documented, solidified further by the Prince of Wales' emotional tribute to his grandmother yesterday afternoon.
His heartfelt statement read: "I, however, have lost a grandmother. And while I will grieve her loss, I also feel incredibly grateful. I have had the benefit of The Queen’s wisdom and reassurance into my fifth decade."
In his first official engagement since receiving his new title, the Prince of Wales spoke to the First Minister of Wales Mark Drakeford on Sunday and recalled his son Prince George's early years.
A statement from Kensington Palace said: "The Prince acknowledged his and the Princess’s deep affection for Wales, having made their first family home in Anglesey including during the earliest months of Prince George’s life".
In a telephone conversation with the First Minister, he vowed to serve the Welsh people with 'humility and great respect' alongside his wife the Princess of Wales.
