They filmed the new Netflix adaptation Agatha Christie’s Seven Dials mainly across the UK, with one key location in Spain.

Main filming locations

  • Bristol, England – Core base for the production, including extensive street work around Bridewell Street (dressed for the 1920s) and interiors at The Bottle Yard Studios.
  • Bath, Somerset, England – Used for several stylish “London” exteriors, especially Great Pulteney Street, Queen Square, and Abbey Green.
  • West Somerset Railway, England – Heritage railway used for the period train sequences.
  • Cardiff, Wales – Some institutional and office scenes, including at Cardiff University’s Chemistry building and other civic buildings in Cathays Park.
  • Ronda, Spain – The dramatic bullring and cliff-side viewpoints (like the Balcón del Cono and the nearby cave shrine) provided the Spanish flashback locations.

Notable “Seven Dials” interiors

  • The Seven Dials nightclub/club itself was created using a historic period building around Queen Square in Bristol, plus the Barrelhouse venue (Clifton Triangle) for the club environment.
  • A stylish restaurant setting was filmed at The Ox, a cellar restaurant on Corn Street in Bristol.
