Campaigners fighting to save the area’s heritage are urging people to sign protest petitions before time runs out.
Lancashire County Council will end all consultation on Monday on the future of Wycoller - the inspiration for Charlotte Bronte’s Jane Eyre, on Burnley’s unique Queen Street Mill and on Helmshore Mills textile museum.
The three are part of a tranch of heritage cuts which also include the Museum of Lancashire in Preston, Fleetwood Museum and the Judges’ Lodgings Museum in Lancaster.
The county council says it will close five museums from April 1st as part of a proposed budget that aims to save £65m over the next two years.
It is understood staff consultations began before the end of December, and statutory redundancy talks with trade unions start this month.
Campaign leader David Morris, of the Friends of Pendle Heritage, in Barrowford, said: “We have just discovered that Lancashire County Council began an official consultation on the cuts on December 10th, and this is now mentioned on its home page. However, the consultation finishes on Monday so if you would like to comment, now is the time!
“Your comments will be anonymous - you only have to indicate whether you are a resident, business etc.
“Please help save Wycoller and the mill museums.
“Tell county councillors what you think.”
