Teachers and governors fear their Grade II-listed primary school will crumble away if urgent repairs are not made.
Those in charge at Stamford Park Primary School in Hale, Greater Manchester, said they felt their needs were being overlooked and, without immediate investment, essential repairs were becoming increasingly difficult to address.
The school, which dates back to 1905, is the only Grade II-listed building in the area and needs between £3m and £4m in funding to get it "up to standard".
Trafford Council said it had been working with Stamford Park but it was a "particularly complex case". The authority added it had received an annual budget of about £2.6m to help maintain 39 schools.
