Dahan-e Gholaman, which is located 2 km from Qala-e-Naw village and 44 km southeast of Zabol city in Sistan and Baluchestan province, was first studied and excavated in 1339 by an Italian archaeologist.
The city is located on a terrace-like height that is 4 to 5 km long. One of the reasons for the construction of this city on the terrace was to prevent the dangers and damages caused by the seasonal and sudden floods of the Helmand River and its sub-branches such as the Senna River.
Another goal was to have and maximize the use of arable land of Dahan-e Gholaman around the terrace for agricultural activities of the people of this city.
The Director-General of Cultural Heritage, Handicrafts, and Tourism of Sistan and Baluchestan Province says: “The results of the excavations show that the remains of Dahan-e Gholaman are at least one and a half kilometers long and 300 to 800 meters wide during the Achaemenid period.”
