Pseudoperipteros

The form is found in classical architecture in ancient Greek temples, especially in the Hellenistic period.

In Roman temples, the pseudoperipteral form became usual, where there were columns behind the portico as well.

If free-standing columns surround the entire building, it is a peripteros.

Unlike a peripteros, a pseudoperipteros has no space (peristasis) between the cella (naos, inner chamber) and the outer walls on the sides and rear, so the engaged columns can also be considered to be embedded directly into those walls of the cella.

The Temple of Olympian Zeus at Agrigento was a famous Greek example of this style.
