View of Kul-e Farah showing the location of the six Elamite reliefs

Sometime around the 9th–8th centuries BCE, the mouth of a gorge opening into the valley of Izeh was selected for the carving of the first of a series of six Elamite rock reliefs depicting ritual ceremonies centered on one or two large-scale rulers, just one of whose identities is known. The site, known as Kul-e Farah, may have acquired religious significance because it housed the source of a seasonal creek, which runs out into the valley. The sequence of reliefs carved on its cliff faces and boulders indicate that Kul-e Farah continued as a locus of ritual and artistic activity into the 6th century BC.
