Iran / Khuzestan Province
The Khusestan province is in the southwest of Iran, bordering Iraq and the Persian Gulf. Ahvaz is its capital, with other major cities including Abadan, Khorramshahr, Shushtar and Masjed Soleiman. As the most ancient Iranian province, it is considered the 'birthplace of the nation'. It is also one of the most ethnic-diverse provinces in Iran. The Karoun river, Iran's most effluent and only navigable river with a length of around 700 km, pass through the city of Ahvaz. Khuzestan is the major oil-producing region of the country and one of the wealthiest provinces in Iran.
Shushtar is an ancient fortress city, approximately 90 km away from Ahvaz. Much of its past agricultural productivity derives from the Roman-built irrigation system which centered on the Band-e Kaisar, the first dam bridge in Iran.
