upon the old propylaea of Peisistratos. These colonnades were almost finished during 432 BC and had two wings, the northern one decorated with paintings by Polygnotus. About the same time, south of the Propylaea, building started on the small Ionic Temple of Athena Nike in Pentelic marble with tetrastyle porches, preserving the essentials of Greek temple design. After an interruption caused by the Peloponnesian War, the temple was finished during the time of Nicias' peace, between 421 BC and 409 BC. Construction of the elegant temple of Erechtheion in Pentelic marble (421–406 BC) was by a complex plan which took account of the extremely uneven ground and the need to circumvent several shrines in the area. The entrance, facing east, is lined with six Ionic columns. Unusually, the temple has two porches, one on the northwest corner borne by Ionic columns, the other, to the southwest, supported by huge female figures or Caryatids. The eastern part of the temple was dedicated to Athena Polias, while the western part, serving the cult of the archaic king Poseidon-Erechtheus, housed the altars of Hephaestus and Voutos, brother of Erechtheus. Little is known about the original plan of the interior which was destroyed by fire during the first century BC and has been rebuilt several times. During the same period, a combination of sacred precincts including the temples of Athena Polias, Poseidon, Erechtheus, Cecrops, Herse, Pandrosos and Aglauros, with its Kore Porch (Porch of the Maidens) or Caryatids' balcony was begun. Between the temple of Athena Nike and the Parthenon, there was the Sanctuary of Artemis Brauronia (or the Brauroneion), the goddess represented as a bear and worshipped in the deme of Brauron. According to Pausanias, a wooden statue or xoanon of the goddess and a statue of Artemis made by Praxiteles during the 4th century BC were both in the sanctuary. Behind the Propylaea, Phidias' gigantic bronze statue of Athena Promachos ("Athena who fights in the front line"), built between 450 BC and 448 BC, dominated. The base was high, while the total height of the statue was . The goddess held a lance, the gilt tip of which could be seen as a reflection by crews on ships rounding Cape Sounion, and a giant shield on the left side, decorated by Mys with images of the fight between the Centaurs and the Lapiths.
