21 October 2026 marks the 60th anniversary of when a colliery spoil tip in Aberfan, South Wales, collapsed after heavy rain. It slipped down the side of a hill, and engulfed Pantglas Junior School and surrounding homes. The disaster claimed the lives of 116 children and 28 adults.
60 years later, the shadow of Aberfan remains deeply etched into the collective memory and identity of the Welsh valleys. It’s a profound reminder of the heavy human toll of the nation’s industrial past.
The landscape of the South Wales valleys is still marked by poorly restored or unrestored opencast mines and coal tips. Recent events, such as the coal tip slips in Tylorstown in 2020 and Cwmtillery in 2024, could have resulted in further loss of life. They serve as poignant reminders of how closely contemporary valley life remains tied to its coal heritage.
Tina Honeyfield and Ralph Connor have been working for more than 10 years on regeneration projects in Cwmtillery. The coal tip landslip of 2024 heavily impacted their home. They shared their thoughts on the legacy of Aberfan and the history and future of Wales’s over 2,500 coal tips:
Although our experience pales in comparison to the unimaginable tragedy of Aberfan, hearing the roar of the tip as it slipped and feeling powerless as the slurry flooded our home gave us a sense of how horrific the events of 1966 must have been.
Tip sites still represent a genuine risk to communities and the same systemic failures are to blame. From the point that coal waste was first discarded on Welsh hillsides to further unbridled 19th century capitalism, remediation has largely been reactive rather than proactive.
With the climate crisis exacerbating risk and local governments woefully underfunded, new approaches must be found to mitigate dangers and we believe these lie in the third sector.
Bringing tip sites into community stewardship and managing them alongside strategic partners for the benefit of people and nature would finally give the people most affected agency over them.
Memorial events, quiet reflections, and commemorative gatherings will take place across Wales this October to ensure that the children and adults of Aberfan lost in 1966 are never forgotten.
Daniel Therkelsen of Coal Action Network said:
60 years on, Aberfan is not just a date in the history books; it is a live part of Wales’ national consciousness.
We welcome the new Coal Tips Safety Authority, but it has a very narrow remit on tip safety. We work with valley communities who continue to feel not enough is being done more generally about the safety risks and environmental condition of opencast scars on their landscape, and complain that the derelict condition of coal tips can attract anti-social behaviour.
The new Disused Tips Authority won’t address these concerns with its current remit – we need the Welsh government to commit to taking action.
Coal Action Network engages with Local Planning Authorities in an initiative to give back to these former coalfield communities the ability to shape and improve access to quality green space over ex-opencast sites and coal tips. This can transform the areas, changing them from liabilities into local community assets.
