Peripteros
A peripteros is a type of ancient Greek or Roman temple surrounded by a portico with columns. It is surrounded by a colonnade on all four sides of the cella, creating a four-sided arcade. By extension, it also means simply the perimeter of a building, when that perimeter is made up of columns. The term is frequently used of buildings in the Doric order.Definition
The peripteros can be a portico, a kiosk or a chapel. If it is made up of four columns, it is a tetrastyle; of six, hexastyle; of eight, octastyle; of ten, decastyle; and of twelve, dodecastyle. If the columns are fitted into the wall instead of standing alone, the building is a pseudoperipteros.
