The operation at Dalton Mills in Keighley has been scaled back as one fire engine and one aerial appliance are damping down the scene.
At around yesterday lunchtime, a fire broke out at Dalton Mills, in Dalton Lane, Keighley, where the likes of Downton Abbey and Peaky Blinders were filmed.
Footage on social media showed flames engulfing the Grade-II listed building.

Over 100 firefighters were on the scene at the height of the blaze, with twenty pumps called out just before midday.
A police cordon was put in place and people living nearby were told to keep their windows and doors closed and say people should avoid travelling to the area.
Dalton Mills dates back to the 19th century and was once the largest textile mill in Yorkshire, employing over 2,000 workers.
A representative for West Yorkshire Fire and Rescue said: “Thanks to local residents and our partner agencies for their support as we tackled the incident.”
Dalton Lane is still closed between School Lane (near Kia Motors) and Riverside and the cordon is still in place.
Bradford Council has said businesses need to report to the officer on the cordon for access to their properties.
No casualties have been reported.
