Coat of arms of the London Borough of Hillingdon

[1] The four green civic crowns or wreaths on the shield proclaim the equal status of the four predecessor units (a borough and three urban districts).

It was adapted by them from the arms of the Paget family, from the reign of Henry VIII's son Edward lords of the manor of West Drayton and later those of Dawley (in Harlington a place also known as Arlington) and of Harmondsworth and Earls of Uxbridge.

[2] The circlet or enclosure of brushwood from which the lion is rising on the crest is from the arms of Hayes and Harlington, and may refer back to its ancient heritage as forested hunting land.

Its wings, with the St George cross, are from the arms of Yiewsley and West Drayton and symbolise the arrival of Queen Elizabeth II at Heathrow airport in 1953.

The blue 'astral' crown on the tiger supporting the shield is in the colours of the Royal Air Force, and celebrates its long history within the Borough.
