The setting of TV hit Byker Grove, which is due to become an Islamic school, has been targeted by vandals.
The windows in the former Bishop’s Palace buildings, now part of the Bahr Academy, were smashed between Thursday night and Friday morning.
When Dipu Ahad, Elswick ward councillor, went to pray at the Benwell building at midday, he found that all the windows had been put out.
Coun Ahad said although no one is sure why the building was targeted, he suspects it was an Islamophobic attack.
“All the windows are smashed, causing considerable damage to a room used for Friday prayers. Nobody could pray,” he said.
“It’s a sad situation, it looks like it is Islamophobic. There’s been a rise in hate crime, especially after Brexit, and people from minority communities are on edge.
“It’s not the first time the building’s been attacked, someone once put a pig’s head inside.”
Police officers were called to the scene but a Northumbria Police spokesperson was unable to confirm if the incident was being treated as a hate crime.
