Agatha Christie’s Seven Dials is a three-episode Netflix limited series based on Christie’s 1929 novel The Seven Dials Mystery. Dramatised by Chris Chibnall (Broadchurch, Doctor Who), directed by Chris Sweeney, and starring Mia McKenna-Bruce, Martin Freeman, Helena Bonham Carter, Edward Bluemel, and Iain Glen, the series is set in 1920s England and follows the spirited Lady Eileen “Bundle” Brent as she unravels a deadly conspiracy involving a secret society. It premiered on Netflix globally on 15 January 2026.
Filming took place across the summer of 2024, with the cast and crew based primarily in the South West of England. Oscar-winning production designer Martin Childs (Shakespeare in Love, The Crown) and filming locations manager Dee Gregson assembled an impressive collection of real historic buildings, heritage railways, and studio sets to bring 1920s England to the screen – often without leaving the South West. A separate shoot in Ronda, Spain, took place in September 2024 for the series’ international scenes. Here is a verified, location-by-location breakdown of everywhere the series was actually filmed.
Main Agatha Christie’s Seven Dials Filming Locations
1. Badminton House – Badminton, Gloucestershire
Address: Badminton, South Gloucestershire GL9 1DD, England
Stands in for: Chimneys — the grand country estate at the heart of the mystery
Scenes filmed: The country house party sequences that open the story; exterior and interior Chimneys scenes throughout all three episodes
Badminton House is the private historic home of the Duke and Duchess of Beaufort, and one of the most recognisable country houses used in British period drama – it previously appeared in Bridgerton. Filming locations manager Dee Gregson described the brief for Chimneys as needing “a substantial country house with extensive grounds – a real ‘big old pile.'” Badminton fulfilled that perfectly. The production spent a significant amount of time on the estate, using both the house’s interiors and its sweeping grounds for the pivotal opening sequences and key scenes across all three episodes.
Visitor info: Badminton House is a private estate. Private garden tours are available from April to September for groups of 15 or more, led by the head gardeners. Check the Badminton Estate website in advance for available dates. The estate is also famously home to the Badminton Horse Trials each May.
2. Westonbirt School (Westonbirt House) – Near Tetbury, Gloucestershire
Address: Westonbirt School, Tetbury, Gloucestershire GL8 8QG, England
Stands in for: Wyvern Abbey – the ominous country home of George Lomax (Alex Macqueen)
Scenes filmed: The second estate sequences including the pheasant shoot, night-time corridors, and interior state rooms
Westonbirt House is a Grade I listed Victorian mansion completed in 1870, now used as a private school. It was a principal filming location for the series and stands out as one of Dee Gregson’s favourite locations from the shoot. “Wyvern Abbey needed to feel distinctly different from Chimneys,” Gregson explained. “Westonbirt School fulfilled this perfectly. It has highly ornate, richly decorated state rooms which the director and production designer immediately responded to.” Filming took place across eight weeks during the summer holidays of 2024, carefully coordinated around the school’s summer programme. The school confirmed its involvement and noted that students and staff were able to watch their building transform into 1920s aristocratic England.
Visitor info: Westonbirt House is a working school and is not generally open to the public. Westonbirt Arboretum, owned by the Forestry Commission, is located nearby and is open to visitors year-round.
3. Bath – Abbey Green and Great Pulteney Street, Somerset
Address: Abbey Green, Bath BA1 1LN; Great Pulteney Street, Bath BA2 4BU, England
Stands in for: The fictional town of Market Basing; London streets including a car chase sequence
Scenes filmed: Martin Freeman’s Superintendent Battle shadowing Bundle at Abbey Green; the car chase sequence on Great Pulteney Street; North Parade Buildings
Bath’s Georgian architecture and period streetscapes made it the ideal stand-in for 1920s England. Abbey Green – a small historic square immediately adjacent to Bath Abbey – was dressed as the fictional town of Market Basing for a key scene in which Battle shadows Bundle and Ronnie Devereux. Great Pulteney Street, Bath’s grandest thoroughfare, hosted the London car chase sequence, with production approaching it “almost like a military operation,” according to Gregson. The whole street was closed to traffic and pedestrians, with period cars filmed driving up and down — and London street signs temporarily installed. Despite extensive preparation, the actual filming in Bath city centre took place across only two days.
Visitor info: Both locations are freely accessible public areas in the centre of Bath. Bath is well served by rail from London Paddington and Bristol. Walking tours of Bath’s period streets are available through local operators and are easy to self-guide.
4. Bristol – The Bottle Yard Studios and City Locations
Address: The Bottle Yard Studios, Whitchurch Lane, Brislington, Bristol BS14 0BH; various city-centre streets, Bristol, England
Stands in for: The Seven Dials Club interior and exterior; 1920s London streets; establishing shots
Scenes filmed: Seven Dials Club interiors (Barrel House); club exterior (All Saints Street and Clare Street); London street scenes (Bridewell Street, Corn Market, Little King Street, Queen Square, Arnos Vale Cemetery)
Bristol did the heavy lifting for the series’ urban scenes. The Bottle Yard Studios – one of the UK’s largest dedicated film and TV studios with 11 soundstages – served as the creative hub for purpose-built sets, including a full recreation of the 1920s Seven Dials neighbourhood of London that no longer exists in its original form. “It was a challenge to recreate Seven Dials,” noted Gregson. “We looked everywhere to try to find that sort of radius of streets.” The nightclub scenes for the fictional Seven Dials Club were filmed at Barrel House, a real Bristol bar and music venue chosen for its stained glass windows and period-feeling wooden booths. The exterior of the club used All Saints Street and Clare Street. Martin Freeman was photographed filming in Bridewell Street, and vintage period cars were spotted around Queen Square and the Corn Market area. Arnos Vale Cemetery provided atmospheric backdrop shots.
Visitor info: The Bottle Yard Studios is a working professional facility and is not open to casual visits. Barrel House, Queen Square, Bridewell Street, and Arnos Vale Cemetery are all publicly accessible.
5. West Somerset Railway – Minehead and Blue Anchor Stations, Somerset
Address: Minehead Station, The Esplanade, Minehead TA24 5BG; Blue Anchor Station, Blue Anchor, Minehead TA24 6JS, England
Stands in for: The period railway sequences central to the mystery’s climax
Scenes filmed: Moving train sequences across unspoilt countryside; the seaside train climax at Blue Anchor Station
The West Somerset Railway – the longest privately operated heritage railway in the UK, running between Bishops Lydeard and Minehead – provided all of the series’ train sequences. The locations team conducted extensive recces along the full line before selecting areas of unspoilt countryside that best preserved a 1920s appearance. Minehead serves as the railway terminus with its Victorian-era features, while Blue Anchor Station – a quiet seaside stop — provided the Hitchcock-inspired climactic seaside train sequence. The Bristol Film Office confirmed both Minehead and Blue Anchor as officially used stations.
Visitor info: The West Somerset Railway operates as a heritage tourist railway and is open to the public. Visitors can purchase tickets to ride steam and diesel trains along the full heritage line. Check the West Somerset Railway website for timetables and events.
6. Cardiff – Crown Court and Cardiff University Science Library, Wales
Address: Cardiff Crown Court, Cathays Park, Cardiff CF10 3PG; Cardiff University Chemistry Wing, Cathays Park, Cardiff CF10 3AT, Wales
Stands in for: Market Basing train station exterior (Crown Court); Foreign Office interiors (Science Library / Chemistry Wing)
Scenes filmed: Exterior scenes of the fictional Market Basing station; scenes in the Foreign/India Office
Cardiff contributed two distinct locations to the series. The Cardiff Crown Court – a modernist building opened in 1966 and part of the city’s civic and legal district – stood in for the exterior of Market Basing railway station, from which the key train journey departs. The Chemistry Wing of Cardiff University, part of the Main College complex on Cathays Park built in the early 20th century, was used to represent the interiors of the Foreign Office, where Ronnie Devereux’s office scenes were filmed.
Visitor info: Cardiff Crown Court is a working court building and is not open to the public for general visits. The Cardiff University Cathays Park campus is a publicly accessible site, though individual buildings require authorisation to enter.
7. Ronda, Andalucía, Spain
Address: Ronda, Málaga Province, Andalucía, Spain
Stands in for: A Spanish location tied to the story’s backstory involving Lord Caterham
Scenes filmed: The opening flashback sequence at the Church of Padre Jesús Nazareno and the Gate of Philip V; the bullring sequence; a cave shrine scene (Ermita rupestre de la Virgen de la Cabeza); the cliff viewpoint Balcón del Cono
Ronda, a dramatic clifftop city in the mountains of Málaga province, provided the series’ Spanish sequences. A separate film unit travelled to Ronda in September 2024 for these scenes, which appear at the very opening of the first episode. The Church of Padre Jesús Nazareno and the Gate of Philip V feature in the flashback sequence involving Iain Glen’s Lord Caterham. The famous Plaza de Toros bullring was used for a pivotal early scene. Episode 2 added the Cave Shrine of the Virgen de la Cabeza, a small church carved entirely out of rock just outside the town, and the Balcón del Cono cliff viewpoint near the bullring.
Visitor info: Ronda is a popular and fully accessible tourist destination. The bullring, the Puente Nuevo bridge, and all city streets and viewpoints are open to visitors. Spring and autumn are the best times to visit to avoid peak summer heat. Ronda is reachable by train from Málaga or Algeciras, or by car via the A-367.
Behind the Scenes: How the South West Became 1920s England
The central production challenge was reconstructing 1920s London and the English countryside without ever leaving the South West of England. As producer Joanna Crow put it: “Bristol, Bath and the wider region offer a rich and varied palette of landscapes and locations. We found 1925 London with no need to time-travel or to leave the South West.”
Oscar-winning production designer Martin Childs built bespoke sets at The Bottle Yard Studios for key interiors — most notably the Seven Dials Club itself, which could not be recreated on a real location because the original 1920s neighbourhood of Seven Dials in London no longer exists in its historic form. The Georgian and Victorian architecture of Bath and Gloucestershire provided the period street scenes, while two entirely different country houses — Badminton House and Westonbirt School — were used to give the two main fictional estates distinctly different personalities on screen. Dee Gregson, the locations manager, worked closely with English Heritage and the owners of multiple private properties across the South West throughout the shoot.
Visiting Guide: Planning Your Seven Dials Location Tour
Gloucestershire (Badminton and Westonbirt)
Badminton House and Westonbirt School are both in Gloucestershire, roughly 15 miles apart, making them easy to combine in a single day trip by car. Badminton is 20 miles east of Bristol; Westonbirt is 3 miles south of Tetbury. Neither is convenient by public transport, so a car is recommended. Badminton House offers group garden tours from April to September. Westonbirt Arboretum nearby is open year-round and is a beautiful complement to the area.
Bath and Bristol
Bath and Bristol are 13 miles apart and connected by regular direct trains (journey time around 15 minutes). Both cities are fully accessible by public transport from London. Abbey Green and Great Pulteney Street in Bath are easily walkable from Bath Spa station. In Bristol, Barrel House (Wapping Wharf area), Queen Square, Bridewell Street, and Arnos Vale Cemetery are all publicly accessible, though spread across different parts of the city — a map or guided tour is helpful.
West Somerset Railway
The West Somerset Railway is a working heritage railway and a destination in its own right. Minehead station is the terminus, and Blue Anchor is a short stop along the line with a quiet beach. Travelling the full line from Bishops Lydeard to Minehead is the best way to see the landscapes used for filming. Check the West Somerset Railway website for seasonal timetables.
Ronda, Spain
Ronda is best visited in spring (April–May) or early autumn (September–October) to avoid summer crowds and heat. The city’s main attractions — the Puente Nuevo, the bullring, and the clifftop viewpoints — are all within easy walking distance of each other. Ronda is reachable by train from Málaga or Algeciras, or by car via the A-367 from the coast.
Estimated Costs
Badminton House garden tours for groups are priced on application — check the estate website. Westonbirt Arboretum charges admission (roughly £10–£15 per adult; check Forestry England for current prices). Walking tours in Bath typically cost £10–£20 per person. West Somerset Railway tickets range from approximately £15 to £30 depending on distance and class. Entry to Ronda’s bullring museum is approximately €10.
Frequently Asked Questions
The series was filmed primarily across the South West of England — at Badminton House and Westonbirt School in Gloucestershire, Bath city centre (Abbey Green and Great Pulteney Street), The Bottle Yard Studios and various city-centre locations in Bristol, and the West Somerset Railway (Minehead and Blue Anchor stations) in Somerset. Cardiff’s Crown Court and Cardiff University also appear. A separate shoot took place in Ronda, Spain, in September 2024.
The fictional estate of Chimneys was filmed at Badminton House in South Gloucestershire, the private historic home of the Duke and Duchess of Beaufort. It was selected by filming locations manager Dee Gregson as the ideal “substantial country house with extensive grounds.”
Wyvern Abbey — the home of George Lomax and the setting for the second estate storyline — is the fictional name for Westonbirt School (Westonbirt House), a Grade I listed Victorian mansion near Tetbury, Gloucestershire. The school confirmed the filming took place across eight weeks in summer 2024. Westonbirt was chosen to feel deliberately different and more ominous than Badminton House/Chimneys.
The interior of the Seven Dials Club was filmed at Barrel House, a bar and music venue in Bristol. The exterior used All Saints Street and Clare Street, also in Bristol. Bespoke 1920s London street sets were also built at The Bottle Yard Studios, as the original Seven Dials neighbourhood in London no longer exists in a form that could be filmed.
All train sequences were filmed on the West Somerset Railway — the longest privately operated heritage railway in the UK. Minehead Station (the line’s terminus) and Blue Anchor Station (a seaside stop along the line) were both used, confirmed by the Bristol Film Office.
The series premiered globally on Netflix on 15 January 2026. It is a three-episode limited series. The production was initially announced under the title The Seven Dials Mystery and was retitled Agatha Christie’s Seven Dials in November 2025.
