Part of the northeast side of this porous peripteral temple has been restored. Both were constructed to a peripteral hexastyle design. It seems that the first peripteral temples were rectangular wooden structures. The temple is a peripteral Ionic ordered temple with 11x6 columns. The Parthenon is a peripteral octastyle Doric temple with Ionic architectural features. If they are surrounded by a colonnade, they are known as peripteral "tholoi". A peripteral colonnade surrounded the temple, which was two rows deep (dipteral). From the early Hellenistic period onwards, the Greek peripteral temple lost much of its importance.
