The Parthenon was built completely of marble from the base of the temple to its roof tiles. It had two large-scale pediments, each filled with over 20, larger-than-life-sized marble figures in compositions that extolled Athena and her power.he Parthenon was an expression and embodiment of Athenian wealth, and it was a symbol of Athenian political and cultural preeminence in Greece in the middle of the fifth century.
The Parthenon stands on the Acropolis, a sacred hill in the middle of Athens. Itâs the big building in the picture below. The other main buildings on the Acropolis are the propylaion (the gateway onto the hill, left of picture), the temple of Athena Nike (victory), and the Erechtheion, a temple to several gods (behind the Parthenon in the picture).
