The protest was against windfarms and the SNP windfarm policy. Organised by the East Fife Turbine Awareness Group, it saw members of other groups with similar views from across Scotland join in.
The group formed at the South Inch and marched through the heart of Perth along Princess Street, St John Street, High Street and George Street before reaching the concert hall.
As part of their efforts, a red airship was flown above Perth's North Inch to demonstrate the height of a turbine.
