Knebworth House in Hertfordshire, stars in episode 4 which airs in December. After location scouting all over Southern England, Knebworth House was chosen. The formal gardens doubled for Kensington Palace Grounds, Knebworths ornate picture gallery became interiors of Buckingham Palace, the lavish library doubled for Windsor Castle and Knebworths elegant dining room became Kensington Palace.
Location owner, Martha Lytton-Cobbald, said "This is one of many filming projects that we have had at Knebworth this year and we have enjoyed working closely and in partnership with them all".
