Where was the series Irish Blood filmed?
Primary filming for Irish Blood took place in Republic of Ireland, specifically Dublin and County Wicklow, with additional scenes shot along Northern Ireland's Causeway coast (Wikipedia (location details)). The choice grounds the show in a specific visual identity—green hills, coastal cliffs, and stone buildings that become characters themselves.
What specific locations in Wicklow were used?
- County Wicklow served as the primary filming base for the series (Wikipedia (location details)).
- The region is known for its dramatic landscapes, including mountains, forests, and coastline.
- Production also used Dublin city locations for urban scenes.
Did the production use Ashford Castle?
- Ashford Castle in Cong, County Mayo was featured as a key location in the series (Wikipedia (location details)).
- The historic hotel and estate appears as a central setting in the mystery.
Viewers get a visual postcard of Ireland, but the specific reliance on a single hotel setting means the show's world can feel contained. For mystery fans, that intimacy is often a strength; for those wanting sweeping variety, it's a deliberate limitation.
The implication: the production team chose authenticity over convenience, using real Irish landmarks instead of studio backlots. That decision pays off in atmosphere, even if it limits where the plot can physically roam.
Will there be a season 2 of Irish Blood?
Yes. The Alicia Silverstone mystery drama was renewed for season 2 on September 8, 2025, the same day as the season 1 finale aired (TV Insider (entertainment news)). The quick renewal signals confidence from the network.
When was season 2 announced?
- Renewal announced on September 8, 2025 (TV Insider (entertainment news)).
- The announcement came hours after the season 1 finale.
What can fans expect in season 2?
- Season 2 will continue the story of Fiona Fox (TV Insider (entertainment news)).
- The series is expected to maintain its six-episode format (Brit + Co (lifestyle and entertainment)).
- No cast announcements for season 2 have been made as of the renewal date (TV Insider (entertainment news)).
The lack of season 2 cast announcements suggests the production is still in early stages. If the core cast returns—and the renewal timing hints they will—expect Silverstone, O'Mara, and the Murphy family to anchor the next arc.
Why this matters: the rapid renewal means the network sees the series as a keeper, not a test. For viewers deciding whether to invest, that's a stronger signal than any trailer.
Is Irish Blood worth watching?
The series has drawn attention for its setting and performances. Here's what the numbers and reviews say so far.
What is the Rotten Tomatoes critics score?
Season 1 holds a critic score on Rotten Tomatoes that reflects mixed to positive reception (Rotten Tomatoes (critic and cast database)). Specific percentage figures are not yet publicly available from the sources provided.
What are viewers saying?
Audience feedback highlights the cinematography and Silverstone's performance as standout elements. The pacing has been a common point of discussion among viewers.
How does it compare to other mystery dramas?
The show leans into a slower, atmospheric style compared to faster-paced mystery thrillers. Its strength is in character-driven storytelling rather than rapid plot twists.
Upsides
- Strong lead performance from Alicia Silverstone
- Beautiful Irish filming locations add visual depth
- Ensemble cast brings authentic Irish talent
- Quick season 2 renewal suggests network confidence
Downsides
- Pacing may feel slow for some viewers
- Limited episode count (6 per season)
- Plot details for season 2 still unknown
- Full cast for season 2 not yet confirmed
The pattern: Irish Blood is a slow-burn mystery that rewards patient viewers. For anyone expecting a fast thriller, the pace might feel deliberate. For those who enjoy character and setting, it delivers.
Who plays Fiona in Irish Blood season 2?
Alicia Silverstone reprises her role as Fiona Fox in season 2 (Wikipedia (cast database)). The character is the series' central mystery-solving protagonist.
Who plays Fiona's father in Irish Blood?
- Jason O'Mara plays Declan Murphy, Fiona's father, in season 1 (Wikipedia (cast database)).
- O'Mara is an Irish actor known for his work in both Irish and American productions.
Who is the actor behind Fiona Fox?
- Alicia Silverstone stars as Fiona Fox (also listed as Fiona Sharpe in some sources) (Wikipedia (cast database)).
- Silverstone also serves as an executive producer on the series (Rotten Tomatoes (critic and cast database)).
The catch: Jason O'Mara's role as Declan Murphy is central to the family mystery. If season 2 explores deeper into the Murphy family tree, his character will be essential.
What hotel is used in Irish Blood?
Ashford Castle in Cong, County Mayo serves as the main hotel location in the series (Wikipedia (location details)). The five-star property is a historic estate that functions as a key setting.
Is Ashford Castle the hotel?
- Yes, Ashford Castle is confirmed as a featured location (Wikipedia (location details)).
- The castle is used as a primary setting for several scenes in season 1.
What other hotels appear?
- No other specific hotels are confirmed in available sources.
- Additional accommodations in County Wicklow and Dublin may appear as filming locations.
Ashford Castle isn't just a backdrop—it's a character in its own right. For viewers planning a trip to Ireland, the show doubles as a tourism advertisement for one of the country's most famous estates.
The trade-off: using a real luxury hotel grounds the series in authenticity but also ties production to a single high-cost location. For season 2, the team may need to introduce new settings to keep the visual palette fresh.

"We are thrilled to continue this journey. The response to the show has been incredible, and we can't wait to share what's next."
— Alicia Silverstone, as reported by TV Insider (entertainment news)
"The Irish landscapes are a character in themselves. The production team went to great lengths to capture the real Ireland."
— Molly McGlynn, director, as reported by Rotten Tomatoes (critic and cast database)
The blend of Hollywood star power and Irish acting talent gives Irish Blood an authenticity that many mystery dramas lack. The central tension is whether the series can maintain that balance as it expands. For American viewers, Silverstone is the draw. For Irish audiences, the local cast provides credibility.
For the network, the decision to renew before season 1 finished airing is clear: commit to the series, or risk losing momentum. For viewers wondering if Irish Blood is worth their time, the cast alone offers a solid reason to watch. The real question is whether Silverstone and O'Mara can deepen the mystery without losing the intimate scale that made season 1 work.
Fans of Irish storytelling on screen may also enjoy revisiting the iconic Irish musical film the iconic Irish musical film, which similarly celebrates Dublin’s vibrant music scene.
