Diamond Jubilee: Queen 'humbled' by celebrations
The Queen has called her Diamond Jubilee "a humbling experience", saying she had been "touched deeply" by seeing so many people celebrating together.
In a message to the nation, she thanked all those who organised the events.
Festivities culminated in an appearance by the senior royals on the Buckingham Palace balcony in front of huge crowds to watch an RAF flypast.
But the Queen's consort, Prince Philip, was absent from her side as he remains in hospital with a bladder infection.
The Earl and Countess of Wessex visited the Duke of Edinburgh on Tuesday afternoon .
Afterwards, Prince Edward said: "He's feeling better." The countess added: "He's in good spirits; he's on good form."
The Queen's message was broadcast on television and radio across the UK and Commonwealth.
"The events that I have attended to mark my Diamond Jubilee have been a humbling experience," she said.
"It has touched me deeply to see so many thousands of families, neighbours and friends celebrating together in such a happy atmosphere.
"But Prince Philip and I want to take this opportunity to offer our special thanks and appreciation to all those who have had a hand in organising these Jubilee celebrations.
"It has been a massive challenge, and I am sure that everyone who has enjoyed these festive occasions realises how much work has been involved."
She added: "I hope that memories of all this year's happy events will brighten our lives for many years to come.
"I will continue to treasure and draw inspiration from the countless kindnesses shown to me in this country and throughout the Commonwealth. Thank you all."
The Queen will continue to mark her Diamond Jubilee on Wednesday after four days of public celebrations.
She will attend a lunch for the anniversary at Marlborough House in Pall Mall in central London with Commonwealth leaders, including prime ministers, governor generals and high commission representatives.
The Queen had been due to be accompanied at the event by the Duke of Edinburgh.
On Tuesday, the Queen attended a thanksgiving service at St Paul's Cathedral where Archbishop of Canterbury Dr Rowan Williams paid tribute to her "lifelong dedication" .
"I don't think it's at all fanciful to say that, in all her public engagements, our Queen has shown a quality of joy in the happiness of others," he said.
David Cameron, who gave a reading at the service , called her "a real inspiration".
"We have seen the country come together with a sense of celebration and unity but also tremendous resilience, resilience from people who want to celebrate despite the weather and resilience, of course, from Her Majesty - nothing stops her doing the job she does," the prime minister said.
US President Barack Obama was among those who paid tribute to her "60 extraordinary years".
In a specially recorded message he called the Queen "a steadfast ally, loyal friend and tireless leader" and said she had been "the chief source of resilience" for the unique alliance between his country and the UK throughout her reign.
