Thus came to an end, the era of the longest reigning British monarch who guarded the prestige of an empire nigh for a century and after 70 years on the throne, Queen Elizabeth II was no more. The United Kingdom and the world is set to bid farewell to the only Queen most have ever known, and the setting is Westminster Abbey, a site that has been paramount for Britain's royal family for nearly a millennium.
In the 1040s, King Edward the Confessor built a stone church on the site of a Benedictine monastery founded around 960, in a major enlargement.
Construction began on the imposing Gothic abbey of today under the orders of King Henry III in 1245.
It was designed as a place for the coronation and burial of monarchs.
William I was the first king crowned in the abbey in 1066 – a tradition which has endured throughout the centuries.
In 1953, Elizabeth II was crowned on the Coronation Chair, as her eldest son Charles will be.
The chair was made in 1300 and 1301. It enclosed the Stone of Scone, which was used for centuries to crown the kings of Scotland.
The stone was temporarily stolen in an audacious raid by Scottish students in 1950, who accidentally broke it in two.
In 1996, with nationalist sentiment rising, it was symbolically returned to Scotland but will come back from Edinburgh Castle to Westminster for coronations.
The abbey has hosted 38 coronation ceremonies for reigning monarchs.
The church has also been the scene of royal weddings – most of them since World War I. The first was when King Henry I married princess Matilda of Scotland on November 11, 1100.
Queen Elizabeth's parents, prince Albert – later King George VI – and Elizabeth Bowes-Lyon, wed in the church in 1923.
And Queen Elizabeth married Philip Mountbatten in the abbey in 1947, bringing some royal colour to the post-World War II recovery years.
Queen Elizabeth's sister, Princess Margaret, and her children Princess Anne and Prince Andrew all got married in the abbey.
The last royal wedding was that of Charles's eldest son Prince William, who married his university sweetheart Kate Middleton in 2011.
Only 14 years earlier in 1997, William attended his mother Diana's funeral in the abbey following her death in a Paris car crash.
It is thought that some 18 British monarchs are buried in the abbey, among 30 kings and queens, starting with Edward the Confessor. King George II was the last, in 1760.
Around 3,330 people are buried at the abbey, among them some of the great figures of British history.
They include Charles Dickens, Geoffrey Chaucer, Samuel Johnson, Rudyard Kipling, Alfred Tennyson, Henry Purcell, William Wilberforce, Laurence Olivier, Thomas Hardy and eight prime ministers.
The ashes of astrophysics giant Stephen Hawking were interred in 2018 between the graves of Isaac Newton and Charles Darwin.
Other notable personalities have memorials in the abbey, including author Jane Austen, Benjamin Britten, Noel Coward, Francis Drake, Edward Elgar, Martin Luther King and Oscar Wilde.
There is a memorial stone to wartime Prime Minister Winston Churchill inside the west entrance.
It sits near the Tomb of the Unknown Warrior, whose body was brought from continental Europe after World War I. The grave represents all Britain's fallen troops. Queen Elizabeth and her mother left their wedding bouquets on the tomb.
The abbey – or to give it its full name, the Collegiate Church of Saint Peter, Westminster – is a "royal peculiar," which means it is exempt from any ecclesiastical jurisdiction other than that of the monarch.
The British sovereign is the supreme governor of the Church of England.
The abbey can regularly seat around 2,200 people, though most will not be able to see Queen Elizabeth's funeral service due to the screen separating the nave from the choir.
The royal family will sit closest to the coffin.
Around 8,250 squeezed in for Queen Elizabeth's coronation, in specially erected tiers.
The central London church played a major role in Queen Elizabeth's life: besides her wedding, it staged her mother's funeral and celebrations of major landmarks in her record-breaking reign.
At services in the church, Queen Elizabeth and Prince Philip nearly always sat in specially made birch chairs presented by the Canada Club in memory of Canadians who fell in World War II.
The monarch has left her mark on the abbey.
Queen Elizabeth's record reign is celebrated in a stained-glass window unveiled in September 2018. Designed by David Hockney, it represents the Yorkshire countryside in the spring.
The sovereign opened The Queen's Diamond Jubilee Galleries in June 2018. Some 16 meters (52 feet) above the abbey floor, they display treasures and tell the story of the church's history.
The abbey is still a working church and holds regular services open to the public.
