Rare listed colliery baths could be pulled down after they were branded a safety risk.
An application has been submitted by Harworth Estates to demolish the pithead baths at the former Lynemouth Colliery.
The facilities were designed in 1938 by Frederick George Frizzell and are one of only two Grade II listed pithead baths in England.
Harworth Estates said it has faced a constant battle against theft, vandalism and anti-social behaviour at the site and no alternative use has been found for the building, which is now a health and safety risk. It says demolition is the only realistic option.
English Heritage is one of a number of groups opposing the plan and has warned that it will have to be referred to the Secretary of State.
