Where was Towards Zero filmed?
Towards Zero was filmed in and around Bristol and the scenic Devon cost.
Bristol Film Office, who supported the filming last summer, explained the different locations that had been used to bring the series to life.
The nave of Bristol Cathedral became the outside of the Westminster’s Royal Courts Of Justice for the BBC show.
The inside of the courts was a mixture of Sessions House in Usk, South Wales, paired with corridors and walkways at Grittleton House, a former boarding school in Chippenham.
The team also shot in Bristol city centre, turning the bustling city into a busy 1930s London street, meanwhile they filmed scenes of Nevile Strange’s flashy apartment at Goldney Hall, one of the University of Bristol’s buildings.
Producers even worked with the VXF company to create a full-scale replica of the Wimbledon court as it was in the 1930s.
The court was built in the Bath & West Showground in Shepton Mallet, but the team filmed scenes in the changing room in Bristol Masonic Hall on Park Street.
Two properties make up Gull’s Point, a private country house in Wiltshire and Tyntesfield House, a National Trust property on the outskirts of Bristol.
In Devon, the Burgh Island Hotel near Kingsbridge became the Easterhead Bay Hotel for the show and the beaches at Bantham, where the Avon meets the sea, and the more sheltered cove at Thurlestone, served as the fictional beaches around Saltcreek and Gulls Point.
Towards Zero starts on BBC One on Sunday, March 2 at 9pm.
