City goddesses ( Stadttychen ), Aphrodite , Cybele and other female Greek heroic figures were depicted with wall crowns, in modern times also personifications of cities and countries. The Roman military decoration corona muralis, on the other hand, is not a republican symbol, but a badge of honor for the storming of a city.
In heraldry, the crown of the wall refers to the drawing of masonry, as it often appears in the coats of arms of free cities and symbolizes the free middle class . If not shown as an exception in the coat of arms , it belongs to the upper coat of arms . It can be designed with three, five or more towers. The latter form is rare. Heraldic animals can run, walk, jump or grow up on the wall crown attached to the coat of arms . Bear , lion , griffin and rooster are known for this . The bearer of the coat of arms is often content with flags or other natural elements.
The way of putting this crown on city arms goes back to the 19th century. It is attributed to Napoleonic heraldry . It has not been widely used because cities prefer to place their crowns on the shield.
