In heraldry, a bar is one of those important figures or charges known as ordinaries. It is formed by two horizontal lines passing over the shield like the fess, but it differs from it in size; the fess occupies a third, while the bar only occupies a fifth of the shield. The fess is also confined to the center, while the bar may be borne in several parts of the shield.
