Visiting Balajadeh, a Spectacular Village in Kordkuy by Marefat Pardis Toos Team

The Great Wall of Gorgan is a Sasanian-era defense system which is located between the southeastern part of the Caspian Sea and the mountains of northeastern Iran in Gorgan, Golestan.

Stretched for almost 200 kilometers along northern Iran, the Great Wall of Gorgan was constructed from 420s AD to 530s AD as a northern frontier of the Persian Empire, ruled under Sassanids. The wall was involved in a series of wars first against the White Huns and later against the Turks. Most parts of the enormous monument are still hidden underneath the surface.
In an ever-changing world of conquest and invasion of the past, defensive walls have often been necessary for cities to survive. The Gorgan Wall and its associated ancient military monuments provide great evidence of the engineering skills and military organization of the Sassanid Empire.

According to UNESCO, the wall is lined by 38 forts which is the longest fort-lined ancient barrier between Central Europe and China, longer than Hadrian’s Wall and the Antonine Wall put together. It is peculiar regarding its physical scale and technical sophistication.

It is 195 km long and 6–10 m wide, and features over 30 fortresses spaced at intervals of between 10 and 50 km. It is surpassed only by the Great Wall of China as the longest single-segment building and the longest defensive wall in existence.
