Wikipedia definition
2. Pier (architecture)In architecture, a pier is an upright support for a superstructure, such as an arch or bridge. Sections of wall between openings function as piers. The simplest cross section of the pier is square, or rectangular, although other shapes are also common, such as the richly articulated piers of Donato Bramante's original plan for St Peter's Basilica (illustration, right).
