Lincoln Castle set up a big screen in its grounds outside for well-wishers to watch The Queen’s funeral, while on the other side of Minster Yard, Lincoln Cathedral set up screens inside for people to witness the funeral.
More than 600 people were in the castle grounds watching the service, while more than 200 filed into the Cathedral.
A spokesman for Lincoln Castle confirmed that around 1,100 people came to pay their respects at Lincoln Castle.
"We opened the gates early – at just before 9.30am, rather than 10am – as mourners were already beginning to gather outside in the square.
“It was a crowd of all ages – including young families – so it was lovely to see the community gather in this way.”
The Queen’s funeral began at 11am at Westminster Abbey where the Queen was married, and later crowned, and then Queen Elizabeth's coffin was driven through London to Windsor Castle, where a committal service was held at St George's Chapel.
Her Majesty will be buried tonight in a private burial at St George's Chapel, alongside monarchs including her father King George VI, The Queen Mother and Prince Philip, The Duke of Edinburgh.
