The township of Ahvaz is situated in the central portion of the province and has a warm and humid climate. Ahvaz is the center and largest city of the province and is located 874 km. from Tehran. In ancient times it was called “Hormozd Ardeshir” and then “Soq-ol-Ahvaz”. Later on it was known as “Naseri”. Some historians have mentioned it as “Algeenis”.
There is a strong possibility that the city of Ahvaz is located on the site of the old city of “Taryana”. Ardeshir Sassanid I rebuilt Taryana and named it “Hormozd Ardeshir”. During his reign and that of his successors, the city prospered, and instead of Susa became the capital of “Suziana” (Khuzestan). At the time that the Arabs gained control of Suziana, Hormozd Ardeshir was renamed to Soq-ol-Ahvaz, which means the market of Khuzis or Hoories.
During the period of Omavi and Abbasides Caliphs, Ahvaz city flourished and became the center for the cultivation of sugar-cane. But at the end of the 3rd century A.H. due to upheavals of Saheb-ol-Zanj it witnessed a decline. Later on efforts were put for recapturing its fame, but in the mid 9th century A.H., the destruction of its large dam further more intensified the decline of the city from the former position that it was used to enjoy.
The construction of the Suez Canal, improved trade and shipping on Karoon River, and reformation of Bandar-e-Naseri as a port during the Qajar era, once again caused flourishing of Ahvaz, and its name was changed to Naseriyeh. During Pahlavi period, the city was re-gained its old name, i.e., ‘Ahvaz’. At present it plays an important role regarding the cultural, economical and industrial fields in Iran as well as being one of the highly populated areas of the province.

Of more interest to tourists are the two ancient cities of Shush (Susa), Shustar and the ziggarat at Choqa Zanbil.

Shush (Susa) & Choqa Zanbil

Now a small, pleasant town, Shush (Susa; biblical Shushan) dates from 4000 years BC and was an strategic Elamite city and a regional capital of the Achaemenid Empire. The town also thrived in the Seleucid, Parthian and Sassanian periods and was an important center of the Christian faith in the 4th century. The city was gradually abandoned during the Mongol invasions.

The ruins of ancient city site (small entrance fee) lie to the south of the modern town. At the entrance is the Chateau de Morgan, a fortress built to defend French archeologists working on the site at the turn of the twentienth century. The ruins of the ancient citadel include a bare 1 foot high (30cm) wall of the Palace of Darius dating from 521 BC and two huge stones from the base of the royal apadana (reception hall).

Shush’s other main attraction is the Tomb of Daniel, the supposed final remains of the biblical, probably mythical, Daniel, an official in the service of King Darius (522-486BC). Ancient Shush, known as Susa, was also the birthplace of Esther – the biblical saviour of the Jews in the time of their captivity in 6th century BC. The town prospered as a Jewish pilgrimage site for over a thousand years throughout the first millenium until the arrival of the Mongols in the thirteenth century. The tomb visitors see today was built in 1871.
