The TV series "Father Brown" is primarily filmed in the Cotswolds, England, particularly in the Gloucestershire village of Blockley. Blockley doubles as the fictional village of Kembleford, with the Church of St Peter and St Paul serving as Father Brown's St Mary Roman Catholic Church. Other notable locations include various Cotswold villages such as Guiting Power, Upper Slaughter, and Moreton-in-Marsh, as well as sites like Sudeley Castle and Winchcombe Railway Station. Filming also extends to places in Warwickshire, Oxfordshire, and Worcestershire, including Princethorpe College, Chastleton House, Broughton Castle, and the Theatre Chipping Norton. The interior sets such as Father Brown’s kitchen and study are filmed at a former hospital in Moreton-in-Marsh. The series selects these picturesque locations to represent the 1950s fictional setting in the Cotswolds.
