The temple of Segesta is 61 meters long (190 feet) and 26 meters wide, built upon 4 steps, with a total of 36 Doric columns supporting the stone roof-frame of the structure. There are 14 columns on each of the long sides of the building and 6 columns across the front and back, for a total of 36 columns. The columns are of a "rough" finish because they were never "fluted." Apparently, the temple was never completed. It also appears that the structure never had a "cella," or roof, and archeologists are still in disagreement as to whether the temple was deliberately planned this way, or was just never finished. It is believed that the edifice was erected between 420 and 430 BC.
