Peripteros

In Classical architecture, a peripteros (Ancient Greek: περίπτερος; see peripterous) 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).

[2] The term is frequently used of buildings in the Doric order.

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.

[1] If the columns are fitted into the wall instead of standing alone, the building is a pseudoperipteros.
