Behind Wales’ sweeping landscapes and proud traditions lies a darker, more unsettling story — one written in whispers, rumours, and cases that refuse to rest.

Welsh Mysteries and Histories uncovers the crimes, disappearances and unexplained events that have slipped through the cracks of mainstream true crime. From chilling unsolved murders to baffling local mysteries, each episode explores stories that still linger in the shadows of valleys, towns and coastlines.

But the unease doesn’t end with crime. Wales is a land shaped by myth, folklore and forgotten histories — tales that blur the line between legend and reality, and continue to haunt the present.

Meticulously researched and told with care, context and deep respect, this is where Wales’ hidden stories are finally brought into the light.
