The placement of various charges may also refer to a number of specific points, nine in number according to some authorities, but eleven according to others. The three most important are "fess point", located in the visual center of the shield; the "honour point", located midway between fess point and the chief; and the "nombril point", located midway between fess point and the base. The other points include "dexter chief", "center chief", and "sinister chief", running along the upper part of the shield from left to right, above the honour point; "dexter flank" and "sinister flank", on the sides approximately level with fess point; and "dexter base", "middle base", and "sinister base" along the lower part of the shield, below the nombril point.
