Shushtar (Persian: شوشتر; also Romanized as Shūshtar and Shūstar, and Shooshtar) is a city in and the capital of Shushtar County, Khuzestan Province, Iran. At the 2012 census, its population was 192,361.
Shushtar is an ancient fortress city, approximately 92 kilometres (57 mi) away from Ahvaz, the centre of the province. 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. The Mayor of Shushtar is Ahmad Asefi.
In the Elamite times Shushtar was known as Adamdun. In the Achaemenian times its name was Šurkutir. The modern name, Shushtar, is connected with the name of another ancient city, Susa (or Shush, in Persian pronunciation), and means "greater (or better) than Shush."
During the Sassanian era, it was an island city on the Karun river and selected to become the summer capital. The river was channelled to form a moat around the city, while bridges and main gates into Shushtar were built to the east, west, and south. Several rivers nearby are conducive to the extension of agriculture; the cultivation of sugar cane, the main crop, dates back to 226. A system of subterranean channels called Ghanats, which connected the river to the private reservoirs of houses and buildings, supplied water for domestic use and irrigation, as well as to store and supply water during times of war when the main gates were closed. Traces of these ghanats can still be found in the crypts of some houses.
The ancient fortress walls were destroyed at the end of the Safavid era.
Band-e Kaisar 
The Band-e Kaisar ("Caesar's dam") was a Roman arch bridge, and the first in the country to combine it with a dam. When the Sassanian Shah Shapur I defeated the Roman emperor Valerian, he is said to have ordered the captive Roman soldiers to build a large bridge and dam stretching over 500 metres. Lying deep in Persian territory, the structure which exhibits typical Roman building techniques became the most eastern Roman bridge and Roman dam. Its dual-purpose design exerted a profound influence on Iranian civil engineering and was instrumental in developing Sassanid water management techniques.
The approximately 500 m long overflow dam over the Karun, Iran's most effluent river, was the core structure of the Shushtar Historical Hydraulic System, a large irrigation complex from which Shushtar derived its agricultural productivity, and which has been designated World Heritage Site by the UNESCO in 2009. The arched superstructure carried across the important road between Pasargadae and the Sassanid capital Ctesiphon. Many times repaired in the Islamic period, the dam bridge fell out of use in the late 19th century, leading to the degeneration of the complex system of irrigation.
People and culture 
The people of Shushtar, called Shushtaris, maintain a unique cultural heritage stretching back to ancient times, and a Persian dialect distinct to their group.
Shushtar New Town 
In 1973, the Pahlavi dynasty initiated efforts to revitalise the economy of Shushtar, which had stagnated since the deterioration of the waterways in the 19th century, and to further develop agricultural resources in the province. The Karun Agro-Industries Corporation built a satellite town across the river from the old city, naming it Shushtar New Town. The primary purpose of this new development was to house the employees of a nearby cane sugar mill, while also intending to stimulate interest in the old city and to provide additional housing necessary to accommodate industrial growth in the province.
Khuzestanis regularly travel to Shushtar to go swimming, boating and kayaking.
