The national flag of Montenegro (zastava Crne Gore) has a red field with gold border and the coat of arms of Montenegro in its center. It was officially adopted on 13 July 2004, when the then Republic of Montenegro was a constituent of the State Union of Serbia and Montenegro, and its precise specification was standardized on 16 September 2004. According to international tradition, when the flag is hoisted together with one or more flags of other states or international organizations on Montenegrin soil, the flag takes the place of honour. The place of honour is considered the center of a circle, the top of a semicircle, the first place in a row, column or a group of flags, the central position between the flags and the left side as seen from the front from the flags of other states or international organizations. The flag is hoisted, lowered and carried with the usual honors (standing up, saluting etc.) The flag can not be hoisted so as to touch the ground, nor should be used as a table cloth, curtain or similar.
