Although often called a coat of arms, strictly speaking the latter is a heraldic design on a shield (escutcheon) or a piece of clothing. This is the central element of a full heraldic achievement which consists of shield, supporters, crest, and motto. Each is unique to an individual or organisation.

For wider information, see the website of the College of Arms, responsible for granting new coats of arms, and maintaining registers of arms.
And for fun, English Heritage offers a heraldry activity, as do various free websites where you can design your own heraldic device.
If you designed your own heraldic device what elements of your identity and values would you choose to include?
If you do devise one, do please share it on the Padlet Wall and explain your choices!
