There is a life-size sculpture of Estimate at the Queen's holiday home.
She loved horse racing so much that she was able to see the person behind the crown.
It was the first time in 207 years that a reigning monarch had owned a gold cup winner. She was in the Royal Box with her racing manager.
He said that a result like that is the end of an amazing journey.
Estimate's victory was one of more than 1,800 victories in her jockey's racing colors. The British Champs Series Hall of Fame will induct the Queen into in 2021.
Racing gave the Queen a chance to relax.
Richard Hannon said that she used to say that it was nice to come to a place that did not smell fresh paint. She kept a copy of the Racing Post newspaper in her purse.

Horses were a part of her life from a young age. George V gave the Queen a pony for her fourth birthday.
She became interested in racing when she accompanied her father to see the royal horses. She said she was able to pat them in the stables. I'd never felt a horse's soft skin before.
Two weeks after the end of the war in Europe, the Queen made her first public appearance at a race meeting with her parents.
She enjoyed a total of 24 victories at the Royal Ascot meeting. Blue was a popular colour for the Queen's hat when she arrived in a procession from Windsor Castle.
It was from her father, King George VI, that Queen Elizabeth II inherited the Royal Stud, a racehorse breeding centre at Sandringham which has produced many of her winners.
She won her first race with Monaveen at Fontwell Park in 1949.
"She recognised her horses by sight, was fascinated by their mental and physical development and always talked in detail to the groom who looks after each one."
She said that the Queen never wore perfume when she visited the yard to see her horses as it can make young colts want to run.
The Queen was a fan of the horse-whisperer Monty Roberts and used his techniques on her foals and yearlings, such as leading them over a blue plastic sheet so they are not afraid of walking through water.
When they arrived at their racing yards, they were better behaved.
She would name the horses with a clear message.
When the Queen was shot at during the Trooping of the Colour parade in 1981 she demonstrated her skills in the saddle.

Sir Michael said she was a pleasure to work with.
He said that training for the Queen came with no pressure because of her understanding.
She was always thinking about what she would do with the animal and who she would breed it to. She was enamored with the idea.
After a win in the King George VI and Queen Elizabeth Stakes, one of her favourite jockeys, Frankie Dettori, shared a joke with her.
I said that it was my fourth King George. The Queen looked at me and said, "Lester won seven." He said that was what he was told.

Four of the British Classic races were won by the Queen.
She won the Oaks in 1977 three days before her Silver Jubilee celebrations and also won the St Leger.
The biggest prize of all was the Derby, which she came very close to winning when Aureole was runner-up to Pinza.
Carlton House was third in 2012 and had another close call.
The Queen will have earned millions of dollars over the years, but much of that is offset by training fees and other costs, and the winnings seem secondary to the fascination of taking part.
Warren said horses were a huge boost for British racing.
If the Queen hadn't been bred into being a monarch, she'd be a horse rider. He said that it was in her genes.
