Khuzestan Province is one of Tourists ‘ destination of Iran Tour . It has many historical and tourism sites. One of these beautiful places is “Shushtar Aquatic Structures”, which was presented to the UNESCO World Heritage Committee by the Cultural Heritage Organization of Iran.

Shushtar is located in the province of Khuzestan, and it can be considered as a museum of buildings and structures that these buildings are interdependent in terms of performance and, therefore, it is a unique city all over the world among Iran Tourism Attractions.

This city was especially valued during the Elamite era  for its proximity to the Chogha Zanbil Temple (one of the biggest temples of that time) and was founded during the Achaemenid era of Mazdarian  of Iran History . Shushtar aquatic system and its structures are based on the time of construction is a technical engineering masterpieces in the world. This masterpiece of engineering is unique both in Iran and in the world.

Shushtar was the capital of the local rulers of Khuzestan during the period of the Parthians, and during the Sassanid era it was considered as one of the most important centers of Khuzestan.

Shushtar aquatic system is based on the time of construction of technical and engineering masterpieces in the world. This masterpiece of engineering is unique both in Iran and in the world.

Shushtar Aquatic Structures is an interconnected set of bridges, dams, mills, waterfalls, canals and massive water guidance tunnels that work in conjunction with each other.

They were built to make more use of water to live easier. This complex was built and used during the Achaemenid era and was continuously used during the Sassanied era. It is considered to be the largest industrial complex before the Industrial Revolution.

The history of making mills and tunnels of this site dates back to the Achaemenid period. The construction of mills in the pre-flooded area of ​​1342 was mostly related to the Safavid period, which was damaged by the flood. The foundation of these mills is related to the Sassanid period, which was restored and restored during the Qajar period.

Shushtar Aquatic Structures Collection is one of the fewest examples to be used for optimal water use in ancient times. The site is a set of dams, tunnels, canals and water mills, which is an industrial-economic complex and in total consists of Shushtar’s water bodies. By studying Iran History and global historical structures, it has been repeatedly mentioned in historical books.

The basis of the work is that the Gargar dam blocks the river. And then in order to fill three tunnels dug in the boulders raise up the water level.

The triplet waters lead to the collection and are divided into several channels that after turning the wheel Mills, water floods into cascades like ponds.

One of the most prominent features of the complex of mills and waterfalls is its proximity to the old and historic texture of Shushtar. In addition to industrial uses, the site also provided water to the residents in dehydrated days.

A very unique and very beautiful visual feature in this collection, with its special fringe, is that the water from the effluent of the mills pours into beautiful pond areas like beautiful waterfalls. It makes a beautiful ceative eye-catching and pleasing landscapes in front of the any viewer.

There is also a beautiful landscape in the backyard. it consists of  the three famous tunnel wells ( Sekoore), the entrance of the city and the” Blity “are.

In addition to the above mentioned, some of the complexities that exist in the design of water supply tunnels are for exploitation other than land use.

The triple tunnels behind the Gargar Bridge have been assigned a certain amount of water to move the mill blades.  It shows that the collection of Shushtar’s mills and waterfalls along the Gargar River is an ancient masterpiece of engineering and engineering.


The Gargar River is completely a manual structure and its construction is attributed to Ardeshir Babakan, the Sassanid king.

But in archaeological studies, this history has fallen behind. The privileged position and proper living conditions in Shushtar, due to its proximity to the Karoon River, provide good facilities for the action being taken in this area.


In the complex of Shushtar aquatic structures, the construction of mills, waterfalls, canals and massive water and cricket guiding tunnels, which are the place to relax and have fun, are remarkable and interesting.

At the far end of the western side of the complex, Sika is located, allowing access to the interior through a few steps. Within this space there is an 8-hole dome with small channels. The water pours through a stream coming out of the Sica wall and is guided through two small channels into the river.

This collection is part of the water supply channels to the mills, which later became a dam in the Qajar period and during the rule of Mohtasham (the local rulers). And in this place, water flows from one part and enters an 8-duct and then enters the two channels through the 8-hole.

There are different views on the meaning of “Sika”. Dehkhoda’s dictionary tells it  is a duck or a kind of a tribal and tribal species of Hinduism, which is a branch of the Buddhist religion.
