Members of the Royal Family were front and centre at the ceremony, many in full regalia, like the Prince and Princess of Wales. They were joined by their children Princess Charlotte and Prince Louis, sitting on the front row of Westminster Abbey.
Their eldest child Prince George is one of the King's pages of honour and walked behind his grandfather as he entered the abbey, helping with his robes.
The Duke of Sussex attended, sitting alongside his cousins Princess Beatrice and Princess Eugenie. His wife Meghan is staying at their California home with their children Lilibet and Archie - who turns four today.
Harry entered with Beatrice and Eugenie and had earlier been seen with cousin Zara Tindall, accompanied by her husband Mike Tindall.
Princess Eugenie, who is expecting her second child, arrived by car with her father Prince Andrew.
Representing the US was First Lady Jill Biden, accompanied by granddaughter Finnegan - the pair were wearing complementary blue and yellow outfits, the colours of the Ukrainian flag.
Their compatriots at the service included singer Katy Perry, who will be performing at the Coronation concert on Sunday. Wearing a lilac skirt suit and an eye-catching flying saucer-style hat, she was accompanied by British Vogue editor-in-chief Edward Enninful as she walked to Westminster Abbey.
Also performing at the concert will be Lionel Richie, who was seen talking to Mayor of London Sadiq Khan as people took their seats in the Abbey.
Richie was invited because of his links to the Prince's Trust charity, set up by the King in 1976. Presenters Ant and Dec were also there in their role as goodwill ambassadors for the charity, which supports young people.
They were seen posing for a selfie inside the Abbey. Dame Joanna Lumley, a friend of the King and Queen Camilla, was also happy to strike a pose for a photograph as she waited to enter the building.
And fellow actress Dame Emma Thompson looked excited by the occasion - or maybe it was the distinctly British weather (rain, and lots of it) that was causing her expression.
Camilla's children, Laura Lopes and Tom Parker Bowles, were at the service with their children. Their father, Camilla's former husband Andrew Parker Bowles, was also among the guests.
And the Middleton family - Catherine's parents Carole and Michael, as well as her siblings James and Pippa - were invited, sitting a few rows behind the Prince and Princess of Wales.
Conservative MP Penny Mordaunt took a prominent role, in her position as Lord President of the Privy Council - she presented the jewelled sword of offering to the King.
The sword, made for George IV's coronation, was exchanged for a bag of 100 newly-minted 50p coins bearing the King's profile, as part of an ancient custom.
Australian singer Nick Cave said he was attending the Coronation for "the stupefying spectacular, the awe inspiring".
Other singers attending included Joan Armatrading.
Prime Minister Rishi Sunak was joined by wife Akshata Murty, with former prime ministers also in attendance - including Boris Johnson, accompanied by wife Carrie. Sir John Major, whose wife Norma was absent, was seen chatting to Sir Tony Blair and his wife Cherie.
There are seven living former UK prime ministers for the first time, and all attended the service.
Dame Floella Benjamin took part in the coronation procession on Saturday.
Other guests from the world of politics include Labour leader Sir Keir Starmer, pictured with Andrew Lloyd Webber, who composed a coronation anthem for the King.
Foreign royals in attendance include Prince Albert and Princess Charlene of Monaco, as well as King Jigme Khesar Namgyel Wangchuck and Queen Jetsun Pema of Bhutan, whose outfits brought a pop of colour to the distinctly grey day.
King Felipe VI and Queen Letizia of Spain, and King Philippe and Queen Mathilde of Belgium, were seen entering the abbey together, colour coordinated in pink.
Foreign leaders present included Canadian President Justin Trudeau, with his wife Sophie, and French President Emmanuel Macron, with his wife Brigitte.
