Warring States Great Wall of Qin Dynasty in Xiji County, Guyuan

The Qin Great Wall (固原战国秦长城) in Guyuan (固原), also known as the Guyuan Great Wall Section (固原秦长城), is a military defense structure that dates back to the Warring States Period (战国) and was further extended during the Qin Dynasty (秦代). Stretching approximately 174 kilometers (180 kilometers in Ningxia), it spans several counties in Ningxia and Gansu, making it a significant part of the ancient Great Wall system. The wall is renowned for its strategic design, which includes rammed earth construction, stone reinforcements in the mountainous areas, and advanced defense systems such as enemy platforms (敌台) and beacon towers (烽燧).

Geographic and Structural Overview

Geographic Location and Stretch

The Qin Great Wall begins in Lintao County (临洮县) in Gansu Province (甘肃省) and extends northeast to Guyuan City (固原市) in Ningxia (宁夏). The wall passes through Xiji (西吉), Yuanzhou (原州), and Pengyang (彭阳), regions known for their strategic importance. It runs along the Hulu River (葫芦河), passing through Xiji County and turning toward Malian Township (马莲乡). The wall finally reaches the Qing Shui River (清水河) in Yuanzhou (原州), where it splits into two lines, one running east and the other southeast, meeting near Sha Wo (沙窝) in Guyuan.

Construction and Materials

The wall itself was mainly constructed using rammed earth (夯土), with sections in more rugged, mountainous areas reinforced with stone or a combination of stone and earth. The base width of the wall is between 6-10 meters, and the remaining height of the structure is 2-10 meters. To increase defense efficiency, enemy platforms (敌台) were placed every 200 meters to offer elevated positions for archers, and beacon towers were built to signal enemy movements across vast distances.

Historical Development

Origins and Early Construction

The wall’s origins date back to the Warring States Period (战国) when the Qin State (秦国) built fortifications to defend its territory. The Qin Great Wall is particularly noted for its role during the reign of King Zhao of Qin (秦昭襄王) in 325-251 BC, when the initial defensive structures were constructed. However, the most significant phase of construction came under Emperor Qin Shi Huang (秦始皇) in 214 BC, when he ordered a major extension to the wall to defend the newly unified Qin Empire from the northern Xiongnu (匈奴) threat.

Repairs and Rebuilds

During Qin Shi Huang's reign, the general Meng Tian (蒙恬) was responsible for overseeing the repair and extension of the Great Wall. Under Meng Tian's supervision, the section of the wall in the Guyuan region was built on top of the older Warring States fortifications. This reinforced the wall's strength and adaptability, transforming it into a formidable defense line.

In 215 BC, Emperor Qin Shi Huang sent Meng Tian with 300,000 troops to fight the Xiongnu, reinforcing the need for a fortified wall along the northern frontier of the empire.

Preservation and Protection Efforts

State of Preservation

The Qin Great Wall in Guyuan remains a remarkable historical site, although some sections are deteriorating due to natural factors such as erosion, as well as human activity like farming and construction. Key areas, such as the Qin Great Wall in Yuanzhou (原州区长城梁), have been preserved well, with nearly 10 kilometers of the wall intact. Many sections are still visible, with sections of the wall rising 4-10 meters high in some places, offering insight into the grandeur of the original structure.

However, parts of the wall have been damaged or destroyed due to human activity. In particular, agricultural expansion has led to some sections being converted into farmland, as seen near the Fuyin Expressway (福银高速), where a portion of the wall has been flattened and turned into arable land.

Preservation Efforts and Projects

In 2001, the Qin Great Wall in Guyuan was officially designated as a National Key Cultural Heritage Site (全国重点文物保护单位), marking its importance to China’s cultural history. Furthermore, in 2017, an emergency reinforcement project was implemented to protect 1,400 meters of the wall. Plans are also underway to create a cultural park at the site, which will include a museum and a designated heritage protection zone.

Architectural Features and Divisions

Inner City and Outer City Walls

The wall in the Guyuan region is divided into two main sections: the inner city (内城) and the outer city (外城). The inner city walls are more substantial and well-preserved, with towering city mounds (城墩) every 200-230 meters. The inner city walls are characterized by their straight lines, imposing structures, and well-maintained state, with some sections still in near-original condition. The outer city, however, has been mostly destroyed, with only mounds and small remnants remaining.

Inner City Wall:

• The inner city wall is 8 kilometers long and remains in good condition.

• The wall features substantial mounds at regular intervals, with a straight line following the natural terrain of the region.

Outer City Wall:

• The outer city wall is mostly destroyed, and much of it has been flattened for agricultural use.

• Only a few mounds (2-3 meters in height) remain visible, offering little to no visible remnants of the original structure.

The Wall's Significance and Cultural Context

Strategic Importance

The Qin Great Wall was built to defend against the Xiongnu (匈奴), nomadic tribes from the north. The wall served as a physical barrier, controlling access to the Qin Empire and maintaining the empire’s frontier security. Beyond its military function, the Great Wall also marked the cultural and technological prowess of the Qin Dynasty, demonstrating its ability to mobilize vast resources for the construction of such monumental structures.

Cultural Legacy

The Qin Great Wall in Guyuan stands as a testament to the military might and the geopolitical strategies of the Qin Dynasty. Its design reflects not only military ingenuity but also the cultural and historical importance of this border region in the context of ancient China’s defense strategies.

Modern-Day Challenges and Future Prospects

Despite its historical significance, the Qin Great Wall in Guyuan faces challenges from agricultural expansion and development. Local farmers often encroach upon sections of the wall, as seen near Yuanzhou District (原州区), where newly plowed fields now sit at the base of ancient Qin wall remnants.

In response to these threats, local authorities have taken steps to stop further damage and have pushed for greater protection. Plans to convert the site into a cultural park and heritage center offer hope for the wall’s long-term preservation.
