50 years ago the mining village of Aberfan was hit by a disaster that claimed the lives of 114 children and 28 adults.
On the 21st October 1966 thousands of tonnes of coal slurry slid down the mountain towards the village of Aberfan.
The slurry hit Pantglas Junior School where students were just beginning their lessons.
Firefighters, emergency services and miners from the local colliery soon arrived at the site to help dig for survivors.
But with the passing hours rescuers began to lose hope of finding more survivors.
Jeff Edwards was the final survivor to be pulled from the rubble just before midday.
Eyewitnesses described seeing the children still sitting at their desks amongst the slurry.
A mortuary was set up at a local chapel in Aberfan where families were forced to identify their loved ones.
The Queen arrived in Aberfan to pay her respects eight days after the disaster.
People from around the world donated to a disaster fund for the people of Aberfan - it eventually raised a total of £1.75m.
The Queen returned to Aberfan in 1973 to open the community centre paid for by donations from around the world.
