Answer 2

Located in Iran, ancient region located southeast of the Caspian Sea. Its capital was Zadracarta.

Gorgân's Defense Wall (155 km long and 6 to10 m wide) is one of the most outstanding and gigantic architectural monuments in "Dašte Gorgân & Gonbad" Steppes history.
This wall which is the largest defensive wall in the world after the Great Wall of China, starts from the Caspian coast, circles north of Gonbade Kâvous, continues towards northwest and vanishes behind Piškamar Mountains

A logistical archeological survey was conducted regarding the wall in 1999 due to problems in development projects specially during construction of the Golestân Dam, which irrigates all the areas covered by the wall.
At the point of the connection of the wall and the drainage canal from the dam, architects discovered the remains of the above wall.
At parts, this wall is 6 m wide and in other parts the width is 10 m, which proves that the thickness of the wall differs in various regions, according to the natural features and soil configuration.
Castles have been built at different distances. The longest distance between castles is 50 km and the shortest is 10 km.The 40 identified castles vary in dimension and shape but the majority are square fortresses.
Due to many difficulties in development and agricultural projects, archaeologists have been assigned to mark the boundary of the historical find by laying cement blocks.
The Gorgân Wall has been named Alexander Dam, Anuširvân Dam, Firuz Dam and Qazal Al'an in various historical texts.
Dr. Kiani who led the archeological team in 1971 believes that the wall was built during the Parthian Dynasty simultaneously with the construction of the Great Wall of China and it was restored during the Sassanid era (3-7th c. A.D.).
