Iwan-e Karkheh: modern name of a Sasanian city, about 20 kilometers northwest of Susa; modern Sorkheh-ye Sheykh 'Aziz.
A large building, excavated in 1950, may have been his palace. The walls were covered with plaster, the building was surrounded by a garden, and it contained a transversal barrel-vault of a type that was to become popular in Christian churches, but has not been attested earlier than Iwan-e Karkheh. This building, which also contained a square hall under a dome, later served as a mosque.
Reports in the western press, published in the summer of 2009, that the site was damaged because it was used for waste disposal, are incorrect. The photos on this page were taken at almost the same time.
If you decide to go, take the road from Andimeshk to Ahvaz, turn to the right to Deloran, and after about fifteen kilometer, when the road forks and the Deloran road leads to the right, turn to the left. By then, you will already have seen the walls. The village between the ruins and the present course of the Karkheh is called Sorkheh-ye Sheykh 'Aziz, "Sheikh Aziz's market".
