Back at Bletchley Park - The Bletchley Circle

More scenes in the hit ITV drama filmed at the Home of the Codebreakers

The crime-solving former Codebreaker characters in the hit ITV drama, The Bletchley Circle, return to Bletchley Park in the second thrilling, two-part story, on ITV from Monday 20 January.

The series, based on the lives of four extraordinary and brilliant women who worked at top-secret HQ Bletchley Park during World War Two, comprises two stories, each told over two episodes. In the second story, we see the women investigate a sinister human trafficking ring. They revisit Bletchley Park but by this time – 1953 – it has become a teacher training college.

Julie Graham, who plays stern Jean, says “It’s always very thrilling to go to Bletchley Park. When you go into these huts you can feel the history. There’s something very humbling about it.

“We also get to play with the real machines they used and that is always very thrilling. There are people with us all the time. Not just because of the safety of the machines, which I’m sure is paramount for them, but because they want it to look as authentic as possible on screen. The staff at Bletchley Park were fantastic and really supportive. It was a great privilege to be able to go there in the first place but they are extremely helpful and welcoming. And it’s wonderful that the success of the TV series has boosted visitor numbers.”

The Bletchley Circle continues on ITV Mondays at 9pm. You can hear more from the cast and crew during filming at Bletchley Park in the Bletchley Park Podcast.
