The Prince of Wales accompanied the King and Queen for a rare joint excursion as a trio to commemorate the 60th anniversary of the Aberfan disaster on Wednesday.
Prince William, 44, Charles, and Queen Camilla joined politicians, survivors and bereaved families in remembering the 116 children and 28 adults who were killed in the mining disaster at the small Welsh village on 21 October 1966.
An entire generation was almost wiped out when 150,000 tonnes of coal waste slid down the hillside before engulfing Pantglas Junior School, following days of heavy rain. Around half the children from the school died in the tragedy.
On Wednesday, the royals visited the Aberfan Memorial Garden and the community centre before joining a prayer to remember those who lost their lives.
Earlier on Wednesday, the King bid a warm farewell to the Sultan of Oman after hosting his state visit at Windsor Castle.
Charles said his goodbyes to Sultan Haitham bin Tarik Al Said at the Sovereign’s Entrance of the royal residence.
The monarch was joined by the Queen, who was wearing a leopard-print dress and shook the Sultan’s hand and told him: "Goodbye. I hope you have a good journey back."
