The heraldic achievement depicted in this photo represents the Coat of arms of Prussia, Germany. Heraldry in Germany has its roots around the year 800 when emperor Charlemagne established the eagle as the symbol of the empire. A heraldic achievement contains multiple components like a shield, supporters, crest, and motto. The most important one is the shield, also called escutcheon, on which we can see the coat of arms as a central element. Also, we can see the coat of arms on a surcoat or a tabard.
