Harlots continues on BBC Two tonight, drawing viewers into the salacious world of sex work in Georgian London.
BBC Two is airing the first season of the hit Hulu-BBC co-production, with two episodes rolling out weekly on Wednesday evenings. The series first aired on ITV Encore and Hulu in 2017.
Fans are eager to learn how the show recreates 18th century London, with the brothels and city streets portrayed in lavish detail.
The raunchy period drama follows madam Margaret Wells (Samantha Morton) and her rival Lydia Quigley (Lesley Manville), who run competing brothels in the capital.
Wells, who used to work for Quigley, sparks conflict when she moves her brothel to Greek Street in Soho in search of a more upmarket clientele, which largely consists of Quigley’s customers.
A turf war ensues as religious evangelists in society seek to shut down the brothels.
So where did Harlots’ filming take place? Let's take a look...
Langleybury Mansion
Much of Harlots was filmed at Langleybury Mansion in Kings Langley, Hertfordshire.
According to The Sun, the house is used for various scenes set in London, including the recreation of Soho’s Greek Street and Covent Garden.
The estate is roughly three miles northwest of Watford, and dates back to 1711.
In 1720, then-owner Baron Raymond, Lord Chief Justice of England and Wales, built the mansion that stands on the site today.
The house and grounds were converted into a school in 1949, which closed in 1996, and has since been used in various film and television productions.
St Trinians, In the Heart of the Sea and The Little Stranger are just some of the titles that have used Langleybury’s stunning mansion to recreate history.
Harlots executive producer Alison Carpenter told Radio Times they wanted to use the exteriors of Langleybury to capture the hustle and bustle of London.
“We absolutely didn’t want it to feel all very interior and dark and fusty, we wanted to feel the scale of London,” she said.
Co-creator and writer Moira Buffini said: “It was always really important that it wasn’t a show that was set in rooms, because London is such a character and it really does come across, this amazing full, vibrant, lively city.”
Chiswick House
Chiswick House, in the London district of Chiswick, was also used to recreate 18th century London in Harlots.
Completed in 1729, the villa was damaged in World War II, but is now maintained by English Heritage.
Historic Dockyard Chatham
According to IMDB, the Tarred Yard Store at the Historic Dockyard Chatham doubled as a tavern in Harlots.
The historic site, just 35km outside of London, is where many historically significant ships were built before heading out into the open ocean.
A maritime museum now sits at the site in Chatham.
Harlots airs on BBC Two every Wednesday at 9pm
