Guy Ritchie’s new Amazon Prime series, Young Sherlock, was filmed across stunning Welsh locations
Amazon Prime’s new series Young Sherlock is a prequel to Sir Arthur Conan Doyle’s iconic Sherlock Holmes stories, starring Hero Fiennes Tiffin, Dónal Finn and Colin Firth. The series which was directed by Guy Ritchie was extensively filmed in Wales, which was apparently quite “a challenge” thanks to the cold Welsh winter.
The cast were spotted filming across South Wales in 2024, with a substantial portion of filming taking place at Great Point Studios in St Mellons, Cardiff, with the production team also utilising the Civic Centre in Cardiff city centre.
Merthyr Mawr Estate in Bridgend County stood in for the Holmes family’s English country estate, whilst Bannau Brycheiniog served as the backdrop for a Chinese village. For the latest TV and showbiz gossip sign up to our newsletter
Young Sherlock is the latest addition to an extensive roster of major TV productions filmed in Wales that have premiered in 2026. Amazon Prime’s Young Sherlock joins Netflix’s Seven Dials with Martin Freeman and Sky’s Under Salt Marsh stars Rafe Spall and Kelly Reilly, all of which have capitalised on the talent and locations Wales provides.
Deon Du Preez, supervising locations manager, told Radio Times: “The Chinese Village, script-wise, was interesting, but challenging. We did not have the budget to build a whole village for those flashback scenes.
“Once we realised the landscape of Brecon Beacons could be the landscape scale we needed, we built a Yurt Chinese Village which looked great.
“Fighting the Welsh winter was a challenge for that build!”
He also highlighted the abundance of Victorian buildings and estates in Wales, along with locations in the south west of England and Oxfordshire, as providing a plethora of budget-friendly filming sites.
Deon shared: “The region has a strong selection of film-friendly Victorian and period locations, including historic streets, civic buildings, heritage sites and country estates.
“Located roughly 25 miles west of Cardiff, Merthyr Mawr is a large privately owned estate known for its 19th Century manor house and picturesque historic village.
“We filmed various scenes throughout the village and within the estate’s extensive woodland areas.”
