Khorramshahr is a city in and the capital of Khorramshahr County, Khuzestan Province, Iran.
Khorramshahr is an inland port city located approximately 10 kilometres (6.2 mi) north of Abadan. The city extends to the right bank of the Shatt Al Arab waterway near its confluence with the Haffar arm of the Karun river. The city was a ghost town in the 1986 census, because of the Iran-Iraq War, but now it is a fairly big city again, as it was before the war.
In ancient times, the area where the city exists today was under the waters of the Persian Gulf, before becoming a part of the vast marshlands and the tidal flats at the mouth of the Karun River.
