The Coat of arms of Leeds City Council derives its design from the seventeenth century.
By the time that the borough was reformed by the Municipal Corporations Act 1835, silver owls had been added both as crest above the shield, and as supporters on either side.
Gold ducal coronets were added to the supporters for further heraldic difference.
[1] In 1974, the county borough was abolished by the Local Government Act 1972, becoming part of a much larger Metropolitan District of Leeds.
The new Leeds City Council continues to use the arms of its predecessor, but to date no application has been made for the formal transfer of the armorial bearings.
