Mapping the Medieval Wall System of China and Mongolia: A Multi-Method Approach (original) (raw)

Unraveling the Mongolian Arc: A Field Survey and Spatial Investigation of a Previously Unexplored Wall System in Eastern Mongolia

Journal of Field Archaeology, 2023

This paper explores, for the first time, a 405 km long wall system located in eastern Mongolia: the “Mongolian Arc” consists of an earthen wall, a trench, and 34 structures. It is part of a much larger system of walls built between the 11th and 13th centuries A.D. The Mongolian Arc, despite its magnitude, has been largely overlooked in existing academic discourse. Our team collected remote sensing data of different types and conducted an archaeological field survey of the entire Mongolian Arc. The different datasets obtained in the lab and the field were analyzed using a geographic information system (GIS). These results were integrated with excerpts from relevant primary sources to provide a preliminary interpretation of the design and potential functions of the Mongolian Arc. Key areas of exploration include the idiosyncratic gaps along the wall, the spatial organization of the wall and structures, and their interrelationship with the adjacent landscape.

Medieval long-wall construction on the Mongolian Steppe during the eleventh to thirteenth centuries AD

Antiquity, 2020

The long walls of China and the Eurasian Steppe are considered to have functioned as either defensive structures against aggressive nomadic tribes, or as elements to control the movement of local nomadic groups following imperialist expansion. This article focuses on a hitherto understudied 737km-long medieval wall running from northern China into north-eastern Mongolia. Built by either the Liao or Jin Dynasties, the wall features numerous auxiliary structures that hint at its function. In research relevant to interpreting other Eurasian and global wall-building episodes, the authors employ extensive archaeological survey and GIS analysis to understand better the reasons behind the wall's construction, as well as its various possible functions.

Identifying Linear Traces of the Han Dynasty Great Wall in Dunhuang Using Gaofen-1 Satellite Remote Sensing Imagery and the Hough Transform

Remote Sensing, 2019

The Han Dynasty Great Wall (GH), one of the largest and most significant ancient defense projects in the whole of northern China, has been studied increasingly not only because it provides important information about the diplomatic and military strategies of the Han Empire (206 B.C.–220 A.D.), but also because it is considered to be a cultural and national symbol of modern China as well as a valuable archaeological monument. Thus, it is crucial to obtain the spatial pattern and preservation situation of the GH for next-step archaeological analysis and conservation management. Nowadays, remote sensing specialists and archaeologists have given priority to manual visualization and a (semi-) automatic extraction approach is lacking. Based on the very high-resolution (VHR) satellite remote sensing imagery, this paper aims to identify automatically the archaeological features of the GH located in ancient Dunhuang, northwest China. Gaofen-1 (GF-1) data were first processed and enhanced aft...

Revealing a Wall with RTK - A Non-destructuve Investigation of a Chinese Medieval Walled Site

Asian Archaeology

A non‐invasive archaeological investigation was carried out using Real Time Kinematic (RTK) topographical survey on the AD 10th to 13th century Kujindui site in Northeast China. The examination of previous documentation and satellite photographs shows the lack of precision on the knowledge of this medieval site. The RTK measurement provided data to draw a topographical contour map and a 3D digital model that reveal the outline of the enclosure wall. It allows defensive architectural features to be reconstructed. The precisely geolocated plan provides the basis for future research and preservation.

The GREAT WALL of CHINA an Architectural Foray

2000 years span the beginning and end of the construction period of the wall. The Wall was often built along the mountain ridges for a better defense. Without advanced technology like today, bricks used to build the Wall were carried by labors and ox carts from the foot of the mountain, which cost a great manpower and money. A lot of labors died because of the heavy work load. The walls are the main bodies of the China Great Wall,and Emperor Qin Shihuang's contribution to the design of the Wall is considered to be of great importance as it ensured peace for the people in the northern part of China against the Huns and established a pattern of defense for future generations. The Great Wall of the Qin Dynasty was built at the expense of many lives.This paper examines the history of the wall and the design and architectural nuances of the wall as present in existing literature.

Detect, map, and preserve Bronze & Iron Age monuments along the pre-historic Silk Road

Central Asia is rich in cultural heritage generated by thousands of years of human occupation. Aiming for a better understanding of Central Asia's archaeology and how this unique heritage can be protected, the region should be studied as a whole with regard to its cultural ties with China and combined efforts should be undertaken in shielding the archaeological monuments from destruction. So far international research campaigns have focused predominantly on single-sites or small-scale surveys, mainly due to the bureaucratic and security related issues involved in cross-border research. This is why we created the Dzungaria Landscape Project. Since 2013, we have worked on collecting remote sensing data of Xinjiang including IKONOS, WorldView-2, and TerraSAR-X data. We have developed a method for the automatic detection of larger grave mound structures in optical and SAR data. Gravemounds are typically spatially clustered and the detection of larger mound structures is a sufficient hint towards areas of high archaeological interest in a location. A meticulous remote sensing survey is the best planning tool for subsequent ground surveys and excavation. In summer 2015, we undertook a survey in the Chinese Altai in order to establish ground-truth in the Hailiutan valley. We categorized over 1000 monuments in just three weeks thanks to the previous detection and classification work using remote sensing data. Creating accurate maps of the cemeteries in northern Xinjiang is a crucial step to preserving the cultural heritage of the region since graves in remote areas are especially prone to looting. We will continue our efforts with the ultimate aim to map and monitor all large gravemounds in Dzungaria and potentially neighbouring eastern Kazakhstan.

The Great Wall as Perilous Frontier for the Mongols in 16th Century

International Journal of Korean History, 2016

The existing scholarship in nomadic-sedentary relations has focused on the raids and invasions by nomads against agricultural society, and has attempted to seek internal reasons for this within the nomadic society. Interactive Ming-Mongol history along the Great Wall in the sixteenth century indicates that the agricultural society was also capable of offense. Many raids conducted by nomads were actually revenge for the provocation and raids by the agricultural society, hence they were retaliatory raids. Nomadic-sedentary groups interacted along the Great Wall area; therefore, scholars should turn their attention to this area rather than exclusively search for reasons from internal factors of nomadic society. The razzias upon the Mongols beyond the Great Wall by Ming generals and their retainers have shown that sedentary society were in need of horses, cattle, meat, wool, hides, etc. Ming China’s big market for the nomadic goods drove Ming generals and their retainers to do the profi...

Blurring the Boundaries: Integrating Techniques of Land Surveying on the Qing’s Mongolian Frontier

This article focuses on the role of spatial dynamics in effectuating the integration of two different sets of land surveying techniques. During the later stages of the Qing-Zunghar wars of the 1690s, the Kangxi emperor (r. 1661-1722) repeatedly asked French Jesuit missionaries, who had been sent to China in 1685 under the patronage of the French King Louis XIV, to join his imperial campaigns targeting the Khalkha-Mongolian borderlands. In the shadow of these imperial journeys, missionaries systematically determined latitudes with Paris-made instruments while Qing officials measured road distances all along the way with graduated ropes. A next step in the evolution of imperial cartographic practice came after the Qing-Zunghar wars had come to an end, when an all-out effort was launched by the emperor to integrate the newly conquered Khalkha Mongols and their lands into the Qing polity. As part of the effort, missionaries were asked to produce a map of the new frontier by integrating European and East Asian practices, which led to the discovery of a technical incompatibility. In 1702, the problem was solved by the precise measurement of the terrestrial degree and, immediately after, the restandardization of the Qing’s most basic unit of length, the chi 尺. Thus, the turn of the eighteenth century saw the crystallization of a new or hybrid Qing cartographic practice, driven by the need to explore the new Khalkha frontier. Selected techniques developed by the French Academy of Sciences were gradually absorbed into a pre-existing framework of Qing land surveying, a process that was shaped and facilitated by exchanges in via throughout the vast Mongolian frontier.
