Residents were joined by their MP and local councillors to protest against development plans for the Leeds Girls' High School site in Headingley.
Greg Mulholland, MP for Leeds North West, said the school's proposals for the Headingley Lane site did not meet the need for green space and public playing fields.

In the next few weeks the Leeds Girls' High School Action Group will release their own planning brief, setting out how they believe the land should be developed.
It comes after the school proposed revised plans for 40 flats and eight terrace to be built on the senior school land, stable block and Rose Court.
Outline permission was also being sought for an unspecified number of homes across the rest of the campus and nearby Victoria Road playing fields.
The school says the changes reduce the density of the proposed development by more than a third and would provide "extensive" public amenity space.
But the school has shelved a scheme for a four to six storey apartment block next to Headingley Business Park.
Paul Fox, spokesman for development consultants Fox Lloyd Jones, has claimed the scheme was "robust and sustainable."
