PIERRIERES, Fr. Heaps of stones, which are designedly collected round fortified places to interrupt besiegers in their approaches. These heaps are covered over with earth to conceal the stratagem; and the spots on which they lie are frequently fortified with palisadoes, in the form of bonnets or saliant angles; so that when the besieger attempts to carry them, the artillery from the ramparts or neighboring places, may be fired amongst the heaps of stones, and considerable damage be done by the fragments that must necessarily fly about.
PIERS. The columns on which the arch of a bridge is raised.
