Knole House moved from Sevenoaks to Switzerland

Knole House in Sevenoaks was transformed into a winter wonderland for Guy Richie's Sherlock Holmes: A Game of Shadows.

When the Swiss location was needed Knole stepped into the limelight.

Jane Maltby, Marketing Manager at Knole, said: "Last autumn the cast and crew from A Game of Shadows came to Knole for five weeks, transforming Stone Court into the courtyard of a Swiss Castle.

"Recreating the wintry conditions of Switzerland required a lot of fake snow and as you might imagine, fake snow does not do as it is told. Whereas real snow tends to sit where it falls, the artificial stuff wanders, particularly in a breeze. This meant that quite a lot of Knole experienced an early dusting of the white stuff.

"Once the drifts of fake snow were in place, Stone Court was used to mark the arrival of Holmes' archenemy Professor Moriarty, by a wonderful horse-drawn sledge.

"We're all delighted to see that this sequence has made its way into the film's trailer - a mere 50 seconds in!"

Every film shot in National Trust places or land generates income for the place in which it was filmed, to continue looking after the historic building or site of natural beauty.

A Game of Shadows which has just been released sees Robert Downey Jr. reprising his role as Sherlock Holmes, and Jude Law returning as his formidable colleague, Dr. Watson.

In the latest instalment the world-famous detective faces criminal mastermind Professor Moriarty (Jared Harris) and the action leads Holmes, Watson and Sim (Noomi Rapace), a Gypsy fortune teller across the continent, from England to France to Germany and finally to Switzerland.
