Buckingham Palace released several official coronation photos of King Charles III and Queen Camilla Monday, two days after the coronation wrapped at Westminster Abbey in London.

The four official photos were all taken Saturday by British photographer Hugo Burnand at Buckingham Palace.

The first photo features Charles seated on a throne chair from 1902 in the palace’s throne room and dressed in “full regalia,” which includes the Robe of Estate and the Imperial State Crown, according to the palace. Charles is pictured holding in each hand the Sovereign's Orb and Sovereign’s Sceptre with Cross.

Camilla is portrayed in the second photo, which was captured in the palace’s green drawing room. The queen was photographed wearing Queen Mary’s Crown and Robe of Estate, according to the palace.

Both Charles and Camilla posed together for the third photo, which was taken in the throne room as well.

The final photo, also taken in the throne room, had Charles and Camilla posing with the working members of the British royal family, including the Duke of Kent, Duchess of Gloucester, Duke of Gloucester, Vice Admiral Sir Tim Laurence, the Princess Royal (or Princess Anne), the Prince of Wales, the Princess of Wales, the Duchess of Edinburgh, Princess Alexandra, the Honorable Lady Ogilvy, and the Duke of Edinburgh, the king’s youngest brother.

The king also released a statement accompanying the photos, expressing his gratitude for the support he and Camilla received over the weekend.

“As the Coronation weekend draws to a close, my wife and I just wanted to share our most sincere and heartfelt thanks to all those who have helped to make this such a special occasion,” Charles wrote. “We pay particular tribute to the countless people who have given their time and dedication to ensuring that the celebrations in London, Windsor and further afield were as happy, safe and enjoyable as possible.”

Charles added, “To those who joined in the celebrations - whether at home, at street parties and lunches, or by volunteering in communities - we thank you, each and every one. To know that we have your support and encouragement, and to witness your kindness expressed in so many different ways, has been the greatest possible Coronation gift, as we now rededicate our lives to serving the people of the United Kingdom, the Realms and Commonwealth.”

The king ended his note with a handwritten signature as well.

Pop superstar Katy Perry took to the stage in front of Windsor Castle in a gold ballgown as she honored royalty.

In the audience, Charlotte, the youngest child of William and Kate, was spotted singing along as Perry opened with her hit song "Eye Of The Tiger (Hear Me Roar)," followed by another hit, "Firework."

Perry was also an invited guest at the coronation service Saturday for Charles.

She revealed onstage that she brought her mom to the coronation celebration and stayed in Windsor Castle.

William, the heir to the throne, honored his father with a speech recognizing Charles' decades of service to others and to the planet.

William was met by loud cheers when he took the stage in front of Windsor Castle.

He honored his father's service, noting the pledge of service Charles gave at Saturday's coronation as well as the "over 50 years of service" he devoted before becoming king.

"We're all so proud of you," William said.

The royal ended his speech by saying, "I commit myself to serve you all, king, country and Commonwealth. God Save the King."

Music star Lionel Richie performed his hit songs Sunday night in front of royalty.

Richie played the piano and sang his hit song "Easy (Like Sunday Morning)" in front of a crowd of thousands, including Charles, Camilla, William and Kate.

He then got up and danced as he sang another hit song, "All Night Long (All Night)."

In addition to performing at the coronation concert, Richie also attended Saturday's coronation service at Westminster Abbey.

As Charles was crowned king, ABC News royal contributors weighed in on the moment.

Robert Jobson said he was feeling "deep pride in my country and the royal family and the clergy."

"Particularly a bit of relief for the king because I thought when the archbishop was trying to get that crown on his head, he was trying a little too hard," Jobson added, with a laugh.

Victoria Murphy commented on how the "mood really shifted."

"It was very solemn, it was quite tense, it felt very serious and then suddenly, it actually feels quite joyous now," Murphy said. "It feels like a moment of celebration."

Sir Peter Westmacott, who previously served as Charles' secretary, said he also felt "a sense of great pride" and is "delighted for my old boss."

"It's a wonderful moment of pageantry and the mixture of humility and service," Westmacott added, "but also the crowning of a monarch in a way that no other country in this world still does or indeed knows how to do as we do."

Ailsa Anderson, who previously served as press secretary to Charles' late mother, Queen Elizabeth II, described feeling "rather emotional about it all."

"However you prepare for something like this, to actually see it has made me swell with pride but also emotional and also proud of my former boss, the Archbishop of Canterbury, who has been faultless in this service," Anderson said. "I think this service is pretty stupendous."

Kristina Kyriacou, who previously served as the communications secretary to Charles and Camilla, said she was "absolutely overjoyed."

"I couldn't be happier. I feel very, very emotional," she added. "This is a king who has worked every second and every hour of the day for the past 60 years. You know, since his teens, he has absolutely worked in public service serving his mother, serving the nation and the commonwealth -- and he deserves this. And I hope everyone understands all the good that he has done and all the causes that he has championed."
