Clandon Park House, an 18th century property in Surrey, England, was engulfed in flames and around 80 emergency service workers battled to extinguish the blaze.

A spokesperson for Britain's National Trust said on Wednesday, "We can confirm that a fire has broken out this afternoon at Clandon Park. The building was evacuated and everyone who was in the house is safe. Surrey Fire and Rescue Service is working to bring the fire under control and we would like to thank them for their swift response. We are devastated to see this happen."

The house was used as a backdrop for Knightley's period drama during filming in 2007.
