Under One Sky, the largest family-friendly community festival in Harrow, began almost decade ago as way to "respond to the cultural richness of contemporary Harrow".

The annual event celebrates the borough's diversity and also its unity and sees between 10,000 and 15,000 people pass through the entrance gate most years.

Harrow Council created the project with the ethos of "joyfulness and creativity" and an emphasis on attracting schoolchildren. There has always been a children's costume parade midway during the afternoon.

The event borrowed its name from a one-off event held around the Millennium called 'Under One Sky' in which giant portable sculptures were paraded from Harrow High School in Gayton Road, Harrow, to Harrow Civic Centre in Station Road.

2014: The former Conservative administration had threatened to cancel Under One Sky or merge it with the 60th anniversary celebrations of the borough and the Labour group - then in opposition - raised a petition of 149 asking for it to be reinstated as a standalone event. When Labour re-took power in May, they pressed ahead with the festival but the lack of time meant it has had to be pushed back in the calendar until September 21.
