Traitors Ireland Series Two Reaches Dramatic Finale as Rachel and Stephen Crowned Winners at Slane Castle
The second series of The Traitors Ireland reached its dramatic conclusion on Tuesday, September 22, with Rachel and Stephen emerging as the winning traitors after a tense and emotionally charged finale at Slane Castle in Co. Meath, as host Siobhán McSweeney presided over one of the most-watched RTÉ programmes of the autumn season.
Background
The Traitors Ireland, known in Irish as Na Fealltóirí, is RTÉ's adaptation of the international social deduction format that has become one of the most successful reality television concepts of the past decade. The show places a group of contestants in a castle setting, where a small number of "traitors" attempt to deceive the majority "faithfuls" while the faithfuls try to identify and banish the traitors before the prize pot is claimed. The format rewards psychological acuity, social intelligence, and the ability to maintain a convincing deception under pressure.
The first series of The Traitors Ireland, which aired in 2025, was a significant commercial and critical success for RTÉ, attracting large audiences and generating substantial social media engagement. The finale of the first series, in which faithfuls Kelley, Vanessa, and Oyin successfully identified and banished the final traitors to secure a prize pot of €42,900, was one of the most-watched RTÉ programmes of that year. The success of the first series made a second series inevitable, and production began at Slane Castle in Co. Meath in early 2026.
The choice of Slane Castle as the filming location for the second series was significant. The historic estate, located on the banks of the River Boyne in Co. Meath, provided a gothic and atmospheric setting that suited the show's aesthetic perfectly. The castle's grounds and surrounding areas were used for the series' elaborate missions, and the production team described the location as ideal for the scale of the television crew and the requirements of the game.
Key Developments
The second series premiered on August 30, 2026, and ran for three weeks before concluding on Tuesday, September 22. The finale, which aired on RTÉ One, saw Rachel and Stephen emerge as the winning traitors after successfully deceiving the remaining faithfuls throughout the series. The outcome differed from the first series, in which the faithfuls prevailed, and generated significant discussion on social media about the strategies employed by the winning traitors.
Host Siobhán McSweeney, who has become one of the most recognisable faces on Irish television through her role in Derry Girls as well as her hosting of The Traitors Ireland, was praised for her performance throughout the series. McSweeney has emphasised the production's commitment to incorporating Irish identity, heritage, and language throughout the game, and the second series featured a number of missions that drew on Irish cultural traditions and history.
The companion show, The Traitors Ireland: Uncloaked, hosted by Kevin McGahern and airing on RTÉ One, provided additional behind-the-scenes content and analysis throughout the series. Reports have emerged that a third series is already in development, with RTÉ expected to confirm the commission in the coming weeks.
Why It Matters
The success of The Traitors Ireland is significant for RTÉ at a time when the national broadcaster is under significant financial and competitive pressure. The rise of streaming platforms has eroded the audience for traditional broadcast television, and RTÉ has struggled to develop original programming that can compete with the global content available on Netflix, Disney+, and other services. The Traitors Ireland has demonstrated that there is a substantial audience for high-quality, distinctively Irish reality television, and its success has provided RTÉ with a valuable commercial and reputational asset.
The show's use of Irish locations — first Ashford Castle in Co. Mayo in the first series, and now Slane Castle in Co. Meath — has also been a positive development for Irish tourism, generating significant interest in both locations from viewers in Ireland and internationally. The Traitors format has been adapted in dozens of countries, and the Irish version's success has raised the profile of Irish television production internationally.
Local Impact
In Co. Meath, the filming of The Traitors Ireland at Slane Castle has been a significant boost for the local economy, with the production crew and cast spending several weeks in the area and generating business for local hotels, restaurants, and suppliers. The castle itself, which is owned by the Conyngham family and is best known internationally as the venue for major rock concerts, has benefited from the increased profile generated by the show. Local businesses in Slane village have reported increased visitor numbers from fans of the show who have come to see the filming location.
What's Next
RTÉ is expected to confirm the commission of a third series of The Traitors Ireland in the coming weeks. The broadcaster has not yet announced a filming location for the third series, though speculation has focused on a number of historic Irish castles and estates. Siobhán McSweeney is expected to return as host, and Kevin McGahern is anticipated to continue with The Traitors Ireland: Uncloaked. The success of the second series has also generated interest from international broadcasters in co-production arrangements that could increase the show's budget and production values for future series.
