In 1978, it was established as the sole National Flag of Greece, and as the war and civil Ensign, and has been used in that capacity ever since.
Blue canton (rectangle in the upper hoist-side corner of the flag) of square shape, five stripes wide, bearing a white Greek cross at its center, with the arms of the cross being one stripe wide.
Canton and stripe elements combined properly, in a harmonious and complementary fashion.
An escutcheon of French 17th Century Style; (near square with rounded lower corners and a gentle tip at its bottom middle) its color azure; (blue of a shade identical to that of the field surrounding it) its border line golden, continuous, discreet; bearing a Greek Cross argent (cross with arms of equal length and of white color) at its center.
Cross formed thus: regular perpendicular lines perform 3x3 division of the escutcheon surface area; corner squares azure; all others argent.
