Prostyle

Prostyle and Prostylos (Greek: πρόστυλος), literally meaning “with columns in front”,[1] is an architectural term designating temples (especially Greek and Roman) featuring a row of columns on the front.

[2] The term is often used as an adjective when referring to the portico of a classical building, which projects from the main structure.

Examples of prostyle include the Temple of Athena Nike, Akropolis, Athens, a prostyle tetrastyle (i.e. with four columns).

This architectural element probably originated in the eastern Greek isles in the 8th century BCE, but there are also many examples in archaic temples in southern Italy.

[3] The subsequent evolution of temple design came with the amphiprostyle, where there are rows of columns both in front and at the back of the temple.
