 Ardashir-Khwarrah was founded by the first Sasanian king Ardashir I (r. 224-242), who around the same time also founded its capital, Gor.Although some sources state that the capital was established after Ardashir's victory in 244 over the Parthian king Artabanus V, archeological evidence confirm that it was established before the battle.In Gor, Ardashir I built a Zoroastrian tower called "Terbal", which was similar to a Buddhist stupa.
