The nation’s support was “the greatest possible coronation gift,” the King has said.
As the weekend of festivities came to an end, the King issued a written message saying: “We thank you, each and every one.”
In the message, the King and Queen pledged to re-dedicate their lives to service.
The King, signing his message Charles R, said he and Camilla give “our most sincere and heartfelt thanks to all those who have helped to make this such a special occasion”.
He added: “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 re-dedicate our lives to serving the people of the United Kingdom, the realms and commonwealth.”
Official portraits of the King and Queen were released to round off the occasion.
The King was shown in his full regalia, wearing the imperial state crown, holding the orb and sceptre with cross, and dressed in his regal purple tunic and robe of estate, seated on a throne chair in the throne room at Buckingham Palace.
The Queen was pictured alongside the King, but also in a solo portrait.
She wore Queen Mary’s crown, with the train of her lengthy embroidered robe of estate spread in front of her.
