In July 2011, over three days of filming, Holdenby House near Northampton was used by the BBC for the exterior set of Satis House. The interior scenes of Satis House were filmed on location in Langleybury Mansion, a former country house and estate near Watford, Hertfordshire.
The Gargery House/Forge was built on marshland to the east of the Essex village of Tollesbury, whilst the village church seen in the opening scenes of the series was the St Thomas a Beckett church, located in the deserted Kent village of Fairfield on the Romney Marsh.
