Drawing by A. Orlandos
On the interior, the cella (main body) of the building is divided into two rooms: to the East the Treasury and to the West the Naos (temple). The Naos is 28.3 meters (93 feet) long, 13.1 meters (43 feet) high with a double row of Doric columns, 23 below and 23 above, separated by an architrave. These columns are 1.14 meters (3.75 feet) in diameter and 6.4 meters (21 feet) high and the upper ones are 68 centimeters (2.25 feet) in diameter and 4.9 meters (16 feet) high. The floor of the colonnade and corridor is raised 4 centimeters (an inch and a half) above the main floor. It is in this room that the 12.8 meter (42 foot) high statue of Athena stands facing the East doors, 6.1 meters (20 feet) from the end columns.
