The Great Wall of Gorgan | The longest historical barrier between Central Europe and China
The Great Wall of Gorgan, a defensive wall, is located in Golestan province, northeast of Iran and south of the Caspian Sea. It stretches almost 200 kilometers and is lined by 38 forts. The Great wall of Gorgan is also known as The Alexander Barrier, The Red Wall and The Red Snake, because its construction materials were red colored bricks. It is inscribed in the UNESCO World Heritage Sites.
The History of the wall
This Great Wall is related to the late Sassanid, and was constructed to defend against the invasion of northern enemies in both mountainous and plain areas in the 5th and 6th centuries and is believed to be a thousand year older than the Great Wall of China.
The architectural features
Having a length of almost 200 kilometers, the wall is made of red bricks. It is a remarkable system both in physical scale and in terms of its technical sophistication. To make the construction works possible, canals had to be dug along the course of the wall, to provide water for brick production. The water of these canals was from supplier canals, which linked to the Gorgan River via Qanats. An evidence of remarkable skills in its construction is that the route of the wall and the canal had to follow a natural gradient. It has around 30 forts, an aqueduct, and water canals that go along the route. There were no stones in the steppe, and this wall is made of dried brick, estimated 2 million in numbers.
Being one of the largest monuments of its kind in the world, it is built by creative and skillful architects. Today, most part of this wall has been ruined over the years.
