WANA (Dec 08) – Artificial intelligence has reconstructed an image of the Great Wall of Gorgan — a structure long buried beneath the ground and considered the second-longest historical wall in the world after the Great Wall of China.

 

Dating back to the Sasanian era, this wall stretched for more than 200 kilometers and featured an advanced water-supply system that secured Iran’s northern frontiers against foreign invasions.

 

Although the massive structure has remained underground for centuries, the presence of several villages built atop it has made excavation and restoration difficult. However, efforts to uncover parts of the wall have recently begun.

Unlike its Chinese counterpart, which was built from stone and rammed earth, the Great Wall of Gorgan was constructed using standardized red bricks.

 

Archaeologists estimate that more than 200 million bricks were used in its construction. The red color of these bricks earned the wall the nickname “Iran’s Red Serpent” in historical texts.

 

Geophysical surveys also indicate that roughly 40 military forts were connected to the wall, effectively turning it into a permanent defensive garrison.
