Nokandeh, an archeologist from Golestan province said that
’Gorgan Wall’ is the second historical wall in the
Asia and the highest historical structure in the Gorgan
region of northeastern Iran.
Nokandeh told IRNA that Gorgan Historical Wall has been
mentioned as ’Anoushirvan Dam’, ’Firouz Dam’,
’Eskandar Dam’ and ’Defense Wall’ in historical
references and scientific accounts.
According to him, the wall extends for 200 kilometers from
Billi Mountain slope in Golestan Forest to Safa Ishan
village in Ghomishan along the banks of Gorgan River.
The main material used in constructing the wall is bricks
measuring 40X40X10 centimeters. Stone is hardly noticed on
the structure.
Archeological studies of the historical wall was first
launched in 1976-1977 under Mohammad Yousef Kiani, which
unfortunately did not continue numerous reasons, he said,
adding that in some sites, the remains of an ancient dam
and water canals were discovered during excavations near
the wall in 1999.
The wall was built during the Parthian Dynasty to protect
mainland ran from invasion by north. It was restored
during the Sassanid era (3-7th centuries AD). Its
construction is contemporaneous with that of the Great
Wall of China, and it is second only to that edifice as
the largest defensive wall in existence.
