Located near Manchester, Lyme House was used in the BBC adaptation of Pride and Prejudice - yup the one with Colin Firth!
You can see the famous lake here where Mr Darcy emerged from swimming but also the courtyard where some carriage scenes were filmed
This is the film Pemberley - the more recent version with Keira Knightley. It's also located in Northern England near Sheffield
If you want to see the real interiors they used for Pemberley then you'll need to visit Sudbury Hall in Derbyshire which is what they used in the BBC tv show
