Campaigners are applying for listed status for a 90-year-old theatre in Scarborough in an attempt to save it from closure.
The Futurist theatre, on the resort's seafront, was built in 1921 and still stages concerts, shows and films.
But the building is in need of repair and the borough council has set up a task group to discuss its future.
A group of local campaigners said they were submitting an application for listed status to English Heritage.
If the Futurist was awarded listed status then listed building consent would have to be applied for in order for any changes to be made to the building.
Patricia David, the group's research co-ordinator, said the Futurist was a building of "real architectural history and interest".
She said: "It does look a mess at the moment, it doesn't look what it really was when it was built.
"It was a gem in the history of theatre in this country."
The Futurist was bought by Scarborough Borough Council in 1985.
A £100,000 subsidy was agreed by the council in November 2009, securing the future of the theatre until at least the end of 2010.
The council said a task group was exploring all options for the building and would prepare a report with recommendations in the early autumn.
