Prince Charles and the Duchess of Cornwall have paid tribute to the country's coal mining past, as they continued their summer tour of Wales.
They laid a wreath at the National Mining Memorial in Senghenydd, as the old colliery hooter echoed around the valley.
Watch the full report by Hannah Thomas:
As part of his visit Prince Charles spoke to some of the relatives of those involved in the mining disaster.
Gwyneth Smart lost her grandfather in the incident. She said it was 'very moving' to have the Prince of Wales visit the memorial.
The couple went on to open the newly re-located Aber Valley Heritage Museum before attending separate engagements in Usk.
