The Light in the Hall is set to return for a second season tonight on Channel 4 and you may be wondering where the hit thriller was filmed.Hayley Anderson Screen Time TV Reporter11:31, 16 Jun 2026The Light in the Hall series two is making its comeback to our screens imminently, but where exactly was the Channel 4 drama shot?‌Over three years have passed since The Light in the Hall, alternatively titled Y Golau, first aired on Channel 4, and now it returns with a fresh narrative centring on a man coming back after two decades in prison.‌Yet having completed his sentence for his cousin's death in the 1990s, could Rhys Owen (portrayed by Mark Lewis Jones) be genuinely innocent of the offence?‌Where was The Light in the Hall season 2 filmed?Like its predecessor, The Light in the Hall series two unfolds in the imaginary Welsh town of Llanemlyn, which is actually the market town of Llandovery in Carmarthenshire.The South West Welsh settlement sits beside the River Tywi and occupies a midpoint between Swansea and Brecon.‌Beyond Llandovery, the surrounding locale of Llandeilo features prominently throughout the Channel 4 series, displaying its lakes and mountainous terrain.Meanwhile, Wales' capital Cardiff provides locations for exterior city scenes and interior filming."I think the world of Golau is really seductive, it's kind of really small town Wales, but with these incredible backdrops, in particular the reservoir," actor Mark Lewis Jones told Radio Times.‌"The landscape is extraordinary, I think. And they're just really great stories."The county of Carmarthenshire is well-accustomed to filming, with numerous programmes and productions shot across the region.‌This encompasses Martin Clunes' series Out There, Willow on Disney Plus, A Discovery of Witches, Keeping Faith, The Edge of Love, Stardust and Doctor Who, to mention just a handful.Producer Nora Ostler Spiteri said: "It has been a pleasure to collaborate once again with Long Story and APC to bring this story to the world."A big thank you to Gwenllian Gravelle and S4C for their warm support and to Sundance Now, Creative Wales and Channel 4 for making this possible.Article continues below"It has been wonderful to collaborate with such a talented cast and crew, and it was lovely to return to Llandovery to bring the world to life."The Light in the Hall season 2 premieres on Tuesday, June 16, at 9pm, on Channel 4.
