The fess vert represents the green spaces in the borough. The torch and quill pen refer to knowledge and the famous writers of the borough (such as Lord Byron, educated at the Harrow School). The pile is drawn from the Chandos arms. The clarion supposedly refers to the borough’s connection with Handel, although he lived in Mayfair.
