In Classical architecture, a peripteros (; see ) is a type of ancient Greek or Roman temple surrounded by a portico with columns. It is surrounded by a colonnade (pteron) on all four sides of the cella (naos), creating a four-sided arcade, or peristyle (peristasis). By extension, it also means simply the perimeter of a building (typically a classical temple), when that perimeter is made up of columns. The term is frequently used of buildings in the Doric order.
