Netflix's hit thriller The Diplomat, is back for season 3 and we couldn't be more excited. After that explosive season 2 ending, there's a lot to look forward to in the eight all-new episodes.
The Diplomat is a show that often gets viewers asking questions. Season 2 had viewers asking just what happened to Margaret Roylin and Ronnie after the dramatic events unfolded, and wondering just what Grove was up to.
Something else those tuning in are always keen to know, is where each season was filmed. We break down the key locations found in season 3 of The Diplomat, and where they can be found in real life.
Where was The Diplomat season 3 filmed?
As with the previous two seasons, The Diplomat season 3 also filmed in both the UK and the US. In the UK, viewers can spot some well known London locations, including Carlton Gardens in St James, and Greenwich's Old Royal Naval College.
Carlton Gardens is a cul-de-sac sitting at the west end of Carlton House Terrace, and was built slightly after the latter. Originally made up of seven large houses, some have now been converted to offices, while others remain luxury residences.
The Old Royal Naval College appears often in the series, standing in for the outside of government buildings. It's no stranger to being featured on screen, having previously appeared in Skyfall, The King's Speech, The Crown and Bridgerton, among many more.
Famous London landmarks Trafalgar Square and Regent's Park can also be seen during season 3 of The Diplomat. The US embassy in London also makes an appearance during the third outing.
For scenes featuring the office of Foreign Secretary Austin Dennison, the show filmed at One Great George Street, Westminster’s corporate conference and events venue.
Excitingly, the series also filmed both interior and exterior shots of the real Foreign Office. "That is a genuine part of the Westminster controlled environment, so [it was] very exciting to be given access," location manager E.J. Richards tells Netflix Tudum.
For scenes depicting 10 Downing Street, the crew were not permitted to use the real location. Interior scenes were filmed at Harefield House in the London borough of Hillingdon - the crew were even allowed to paint the walls here, to recreate Downing Street as it really appears.
Exterior shots for 10 Downing Street were filmed at Elstree Studios in Borehamwood, where the iconic street was built as a set.
Is Winfield House a real place?
In the show and real life, the diplomatic residence for the US ambassador is Winfield House in Regent's Park. However, the real Winfield House isn't used for filming, with Wrotham Park in Hertfordshire being used instead.
Found in the South Mimms area of the county, Wrotham Park is a Palladian Mansion set in a 2,500 acre estate. It was designed by Isaac Ware in 1754 and built by Admiral John Byng, the fourth son of Admiral Sir George Byng.
Where is The Diplomat season 3 filmed in the US?
In the US, the Coe Hall Historic House Museum in Upper Brookville stands in for Prime Minister Trowbridge's home. The museum is part of the larger Planting Fields Arboretum State Historic Park and features a 65-room Tudor Revival mansion.
"One of our greatest achievements of Season 3 was discovering and gaining access to film at Coe Hall Historic House," location director Rob Coleman told Tudum - the mansion had previously allowed very little filming to take place there.
The museum closed for two months while filming took place. "It was one of the only homes we scouted because we all knew early on that it was the right fit," Coleman adds.
If you want to know where to find The Penn mansion from season 3, it's actually the Seacroft Estate on Centre Island, New York (Long Island). Owned by the same family for five generations, Coleman reveals shooting there was "an amazing filming experience."
For Season 3, all interior Washington DC locations were filmed in New York City, mainly at the DeSeverky Mansion in Old Westbury, New York (Long Island). Some scenes were also filmed at the library at the Lotus Club in Manhattan because of the appropriate federalist architecture.
While the majority of season 3 filmed on location in London, production moved to New York to allow Keri Russell and Debora Cahn to balance the shoot schedule with their families.
Speaking to WWD, Keri says, "She [Debora] had always pitched the show to me as starting in London and then being able to come home. And what we did is just moved anything that shot inside a stage back to New York so that our children didn’t forget who we were."
Of filming in the UK capital in the future, the actress adds, "we still plan on going back to London, and we both love London so much, so we still plan on going back and we still plan on having location porn. It’s the fantasy of the show."
All three seasons of The Diplomat are currently available to watch on Netflix.
