The school building has been used as an Islamic Centre since 1996
A special meeting to decide whether to build a mosque in Camberley is to be broadcast on the internet.
Surrey Heath Borough Council will broadcast the planning meeting, which is being held at Camberley Theatre in Knoll Road, on its website.
The local Bengali Association wants to build a mosque on the site of a listed former school building.
Local historians and residents have argued the town's heritage must be protected and are opposing the plans.
About 350 people are expected to pack into the theatre with entry on a first-come first-served basis.
All 40 councillors will consider the application to knock down the listed Victorian school building in London Road, which is about half a mile away from the Royal Military Academy at Sandhurst.
'Dome and minarets'
It was originally home to Yorktown Infants and Primary schools, before later becoming St Gregory's Roman Catholic school.
When the school closed, the building was sold to the Berkshire, Hampshire & Surrey Bengali Welfare Association which has been using it as an Islamic Centre since 1996.
The association has said the building no longer meets the needs of the growing local Muslim community, and people would like to be able to worship in a mosque and not in a school.
Under the plans, the existing building would be demolished and a purpose-built mosque with a domed roof and two minarets would be put up in its place.
The meeting will be broadcast on the borough council's website from 1845 GMT on Wednesday.
