Located in Iran's Sistan-Baluchestan province, the city of Dahaneh-Gholaman two kms from Ghal'e-Nau village in the suburb of Zabol is one of the provincial touristic attractions.

According to reports by IRNA, a great number of ancient sites and demolished monuments dating back to various historical eras such as the Sassanid and Islamic period mark the existence of a rich culture and civilization in the area.

History experts believe that the monuments in Dahaneh-Gholaman are set up on a range of natural heights 1.5 kms in length and 300-800 in width adjacent to the remains of Senroud dry and old delta.

No material and cultural objects such as earthenware are seen in the historical city of Dahaneh-Gholaman, except a few worn-out and broken pieces of ceramics.

The supervisor of the archaeological excavations Mansour Seyed Sajjadi told IRNA on Wednesday that the survey and excavations in the area bring to light the evidences of a large city in the area.

"The objects unearthed in the site are classified into a group of major monuments and some individual buildings," he added.

He added that the remains of a big monument is unearthed at about two kms to the south of the ancient city, which served as a garrison.

The long thick walls of the big square monument are 200 ms in length and about 3-4 ms in width.

Sajjadi said that the city lived a short life ranging between 150-200 years in the fifth and sixth centuries.

"Given that Dahaneh-Gholaman was constructed on a pre-planned design and special objectives, it serves as a remarkable sample for studying the history of urbanization trend in ancient Iran.
