In heraldry, a pile is a charge usually counted as one of the ordinaries (figures bounded by straight lines and occupying a definite portion of the shield).
It consists of a wedge emerging from the upper edge of the shield and converging to a point near the base.
A few heraldry authorities from the Middle Ages such as Sir Thomas Holme and Nicholas Upton believed that whenever piles issued from the chief, they should automatically meet in point, but this view eventually fell out of favour and it has become common practice that unless otherwise specified, they should be drawn perpendicularly.
[2] Like any ordinary, a pile may have other charges on it, may have its edges ornamented by any of the lines of variation, and may have any tincture or pattern.
The arms shown here, for the Elsenburg College of Agriculture, was blazoned by the South African Bureau of Heraldry as Per pile embowed inverted throughout gules, vert and argent; dexter a single share plough and sinister a garb, or, in base an anchor azure, cabled gules; but it could as easily be blazoned as Per pale gules and vert; on a pile inverted embowed argent, between a plough and a garb Or, an anchor azure cabled gules.
