It also used some of the columns and metopes that were going to be used for the old Parthenon. Some people think that Athens built the Parthenon to show the Persians that they weren't scared of them any longer as well as to put themselves above the other Greek cities. The design of the Periclean Parthenon was greatly influenced by the older Parthenon. Looking at a plan of both the older and the newer Parthenons you can see very clear aspects that are similar and different between the two. The location and general size are very similar along with the basic arrangement of the plan and elevation.
Some differences are an enlarged platform and added columns.
One extra column is added on the sides while two are added on both ends. Part of the reason they increased the size is so it could house the huge gold and ivory statue of Athena . There were aisles around the interior of the cella so the privileged could walk all the way around this statue. Although the Parthenon is viewed as the high point in Doric Architecture it is not purely Doric. Saying that it is the high point means that Doric architecture was perfected in the Parthenon.
