Oakham Enterprise Park briefly went back to its time as a prison when a BBC film crew came to town to shoot scenes for police drama Happy Valley.
A spokesman for the production crew said the site was “amazing,” adding: “The cells and corridors are all still intact and look well worn.”
The council’s portfolio holder for development Terry King (Con) added: “We’re extremely pleased to welcome the cast and crew of Happy Valley to Rutland.
“Oakham Enterprise Park is now renowned as a great location for production companies working on film and television projects of all sizes. This is a great advertisement for the County and makes a valuable contribution to our local economy through trade and tourism.”
