It was eight days after the horrific events at Aberfan that the Queen, then aged 40, arrived to see the devastation herself.
Seeing the impact of the tragedy first hand started a lifelong link between the Queen and the community. As well as that visit in 1966, days after the tragedy, she visited again in 1973, 1997 and 2012. She sent a heartfelt message to a commemorative event in 2016.
During her visit, she was handed a posy from a young girl which she described 50 years later as "heart-breaking". The inscription attached read: "From the remaining children of Aberfan".
