The victims of Wales's mining disasters will be remembered tomorrow on the 100-year anniversary of an explosion that killed hundreds of people.
The Senghenydd colliery disaster, when 439 miners were killed by a gas explosion, is the worst accident in British mining history.
To commemorate the October 1913 tragedy, and to remember everyone killed in mining in Wales, Aber Valley Heritage Group has organised a day of activities to recognise the impact the Senghenydd deaths had on the small mining community.
The event will begin with the sounding of the original universal colliery pit hooter which will ring out down the Aber Valley at 8.10am, just as it did 100 years ago, Caerphilly County Borough Council said.
A dedication service will be held at 11:30am in a new memorial garden followed by the unveiling of a bronze statue, designed by sculptor Les Johnson, depicting a rescue worker coming to the aid of one of the survivors of the explosion.
The event will also see the opening of a walled garden on which individual tiles featuring the name, age and address of all those killed in the Senghenydd disaster will be mounted.
The ceremony will also see the unveiling of a wall of remembrance dedicated to those who lost their lives in the disaster, featuring individual ceramic tiles detailing the name, age and addresses of each victim.
The memorial garden will have a "path of memory" dedicated to all mining accidents across Wales in which five or more people were killed. T he path will have tiles listing the colliery, date of the disaster and the number of people who died, along with a bespoke tile acknowledging those killed in other mining accidents.
Jack Humphreys, chairman of the heritage group, said: "It has been a hundred years since the disaster at the Universal Colliery, but the impact that the explosion had on this small mining community is still felt today. We hope the event planned for Monday 14th October is a fitting tribute to the victims of the explosions in Senghenydd and mining disasters across Wales."
