The dedication of the present temple ruins, the largest religious building in the entire Roman empire, dates from the reign of Septimus Severus, whose coins first show the two temples. The great courts of approach were not finished before the reigns of Caracalla (211-217 CE) and Philip the Arab (244-249 CE). In commemoration of the dedication of the new sanctuaries, Severus conferred the rights of the ius Italicum on the city.Today, only six Corinthian columns remain standing of this huge Jupiter temple.
