The Prince of Wales, The Duchess of Cornwall, The Duke and Duchess of Cambridge and Prince Harry, along with the Prime Minister were among the 1,500 who attended a central London ceremony to remember those who passed away in the Grenfell Tower fire.
Hundreds of mourners paused for a moment of silent reflection on their way out of a ceremony at St Paul's Cathedral to mark six months since the tragedy.
Bereaved families and survivors of the Grenfell Tower fire are now "a family", a man who lost his uncle has said.
He said: "The Royal Family being there as well, we appreciated that a lot - a day to remember our loved ones and to remember that great disaster and hopefully try and move on from it and learn from it, so we're not sitting here in the future remembering other ones that lost their lives that shouldn't have.
Appearing emotional, he continued: "We should never have been here today, our friends, our families should never had died, but we're all here together, remembering them.
"It feels like it's been six hours. That day stays embedded, so fresh in the mind - it's hard to turn it off and turn it away.
"It's just been awful, like a big abyss.
"But now, all of this anger and frustration and sadness has been turned into determination - determination for justice, to make sure our loved ones are not forgotten, that the people who are responsible are held accountable and changes are made so this never happens again."
The Bishop of Kensington told the community at the heart of the Grenfell Tower fire of his hope that the tower may one day become "a symbol of the time we learnt a new and better way".
He told survivors and those who lost family members in the blaze that he hoped that Thursday's national memorial service would assure them that the nation had not forgotten them.
Bishop Tomlin said to the congregation at St Paul's Cathedral: "My hope, my prayer is that today we will pledge ourselves to change, from a city where we didn't listen, where we didn't hear the cries of our neighbours because we were too wrapped up in our own interests and prosperity, to create a new type of life together, where we are turned not inwards to ourselves, but outwards towards each other: a society known for listening, compassion and love.”
