S4C, TG4, MG ALBA partner on docuseries The Wall

March 26, 2026

S4C, TG4 and MG ALBA have joined forces on a second season of documentary series The Wall (4 x 60’), marking the first tri-nation co-production between the three Celtic-language broadcasters.

Produced by Welsh indie Rondo Media, in partnership with Irish producer Rosg and Scottish Gaelic producer Hamish Macleod, the series explores the human impact of borders and divisions around the world. The project is supported by Welsh Government via Creative Wales and distributed internationally by Cineflix Rights.

Filmed across four continents, the series takes viewers to the Finnish-Russian border, São Paulo in Brazil, Vietnam and the Spain-Morocco frontier in Ceuta, exploring how walls and borders shape the lives of communities living on either side.

Each commissioning broadcaster will be supplied with its own language version, with presenters working across Welsh (Y Wal), Irish (An Balla) and Scottish Gaelic (Am Balla), while an international version is narrated by Matthew Rhys, who also voiced the first series. TX for the Y Wall has been confirmed as April 7th on S4C.

Commissioned by Llinos Wynne (S4C), Proinsias Ní Gráinne (TG4) and Margaret Cameron (MG ALBA), the project reflects growing collaboration between Celtic broadcasters and demonstrates how minority-language networks can work together to deliver ambitious international storytelling.

Llinos Wynne, Head of Documentaries and Factual at S4C, said: “This collaboration between S4C, TG4 and MG ALBA demonstrates what can be achieved when Celtic broadcasters work together. By pooling creative talent and resources, we can tell ambitious global stories while celebrating our shared cultural heritage.”

Across four films, the series explores stories of identity, migration and reconciliation, meeting individuals living in the shadow of physical and invisible walls, from heavily fortified borders to divisions created by wealth, history and conflict.

The series examines how communities navigate these divides, while also highlighting the extraordinary lengths people go to bridge them.

Proinsias Ní Ghráinne, Commissioning Editor at TG4, commented: “Projects like this show the strength of collaboration between broadcasters working in minority languages. Series 1 was a hit on TG4 and was distributed to over 100 territories worldwide. The Wall is another powerful series that reflects both local perspectives and global realities.”

Margaret Cameron, Director of Content at MG ALBA, said: “Working with our partners in Wales and Ireland has created a genuinely collaborative production that highlights the strength of Celtic-language storytelling on the international stage.  It’s a series that speaks to our times. The production was filmed simultaneously in multiple language versions, with presenters and crews working together throughout the shoot, comparing languages, discovering shared Celtic roots and forging what the production team describe as “one extended Celtic family telling urgent global stories together.”

Catherine McCormick, VP Acquisitions, Cineflix Rights, added: “The global nature of the stories covered in the first season of The Wall resonated well with audiences around the world, so we are delighted to be partnering once again with the Rondo Media team to offer this second season to our international buyers.”

In an increasingly competitive global television landscape, the tri-nation collaboration behind The Wall demonstrates how partnership between Celtic broadcasters can strengthen minority languages while delivering television with international scale and impact.
