The town and its surrounds were featured throughout episode one of the show - including a panoramic shot from the sky showing Devonshire Dome and other landmarks.
In one scene character Fiona Grayson and her partner Geoff pull-up in Market Place - with a view of Eagle Parade in the background.
Camera crews descended in and around Buxton and Castleton in late January and early February last year - causing altered parking restrictions and some temporary traffic control measures.
The show’s executive producer Chris Lang told how crews were just four-weeks shy of completing principal photography when the pandemic hit - however filming resumed in September.
Finally airing this week, the show stars BAFTA-nominated actors Nicola Walker and Sanjeev Bhaskar as DCI Cassie Stuart and DI Sunny Khan.
The six-part series charts a fresh investigation into another emotionally-charged cold case murder.
High Peak scenes centre around family therapist Fiona Grayson, partner Geoff and their two children.
She is one of a number of suspects in the case, all at one time known to each other but now dispersed across the country and living completely separate lives.
Speaking about Fiona, actor Liz White describes her as doing “a good job re-establishing herself but the past is still hanging over her head”.
She said: “She always thought she would tell her partner the truth when the time was right but life got in the way a little and it never happened.”
The show goes out on ITV every Monday at 9pm.
