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. If it touches the base, it is blazoned throughout.
Though the pile issues from the chief (upper edge) by default, it may be specified as issuing from any other part of the edge or as extending from edge to edge of the shield. Although it is not supposed to issue singly from the base, this rule is frequently ignored.
a pile reversed (or inverted or issuant from the base). If not drawn high enough, it can be confused with a division of the field per chevron. See the coat of the Asper Foundation, Canada.
a pile throughout (or entire), reaching from one edge of the shield to the other. See coats of Tidd family, Canada.
