City wall is an important symbol of ancient Chinese cities with unique geographical and cultural characteristics. Thus, the preservation of this historic landmark is considered significantly important. However, numerous residential construction activities and changes in ecological environment have destructed a great portion of the city walls in recent years. This study looks into the preservation of the ancient city walls from the systematic perspective and in line with the actual characteristics of Longdong Region to provide guideline measures for the protection and restoration of such landmark. Cognition and preservation are adopted extensively to investigate the specific situation of and the factors that influence the ancient city walls in this region. Preservation strategies for the city walls, including the “Axis-Point” system, planning control, and authenticity readability, are presented. The ancient city walls in Longdong Region can be preserved by protecting the entire region, the city, and the main wall body. The systematic method and preservation strategies at the “macro perspective,” “medium perspective” and “micro perspective” levels can solve the preservation problems of the ancient city walls in Longdong Region effectively.

To commemorate the 100th anniversary of the Xinghai Revolution, the government of Wuchang district in Wuhan City intends to rehabilitate rain-wind corridor, feudal pavilion and the city walls. After access to historical data, site survey, mapping, photographing and measuring, the rehabilitating engineering program of rain-wind corridor, feudal pavilion and the city walls of the Wuchang Uprising Gate is achieved. In the fourth year of Hongwu (1371), Ming dynasty, Zhou Dexing, the duke of Jiangxia, built Wuchang city on the basis of Yingzhou city of Tang dynasty. Wuchang city has large scale. In Ming and Qing dynasty, it was the legacy of county, town, city and province. Its diameter from the east to the west was of 2.5 km, with 3 km from the north to south. The thickness of wall foundation is 22.44 m, with top thickness 17.82 m. Nine gates were designed for the ancient city. The Uprising gate, one of the nine gate of the Wuchang ancient city, was opened to the south and also the busiest gate for entering the city. New Army Engineering Battalion of Hubei took the lead and fired the first shot. And then they occupied Zhonghe Gate and Chu Wangtai to welcome the South Lake artillery, Ma team and other revolutionaries.

Quanzhou in south-eastern China was built in the Sui Dynasty, having more than 1,000 years of history. Its urban development led to the triple walls in a different period of time. Its unique landscape of multiple walls is a one of the Chinese ancient city patterns. However, the massive stone-built city wall pattern like Newcastle also has more than 1000, years of history in western cities .City walls maintain the preeminence as the city’s most powerful fixation line. The expansion of the wall in Quanzhou shows how the time-space changes, while Newcastle' s fringe belt is relatively stable, which forms a different urban form. This article mainly compares the following aspects: (1) The development of Quanzhou fringe belt; (2) Differences of fringe belts between the multiple walls city and the sole wall city; (3) Differences of land use in intramural zone between two cities. This paper analyzes the differences of fringe belts caused by city walls between Quanzhou, (China) and Newcastle, (England), and their influence on the urban form between the East and the West.

Insight Into

Six inscriptions relating to the construction of the fortifications of the southern Italian town of Telesia were analyzed and compared to three inscriptions of the same type from the Italian town of Grumentum. The purpose of this was to gain insight into how Italian towns funded and organized the construction of city-walls during the Late Republic. The city-walls were built progressively in both towns, and in both cases were probably funded by private citizens, even if they were acting as magistrates. In Grumentum an older city-wall was gradually replaced by letting each new, annually elected magistrate build a new section. It would seem that in Telesia the walls were built first. The subsequent construction of the towers probably followed the plan of the local senate and was paid for by the magistrates themselves. The expressions pro ludeis/ludis on some inscriptions suggest that they were built instead of giving games.

L. F. Marsigli represented three archaeological structures on the map of Colonia Ulpia Traiana Sarmizegetusa, made in 1699 and published in 1726 – the city walls, the amphitheatre and a rectangular, double-walled building which encloses an empty space, and which has a square-shaped niche on one side (Pl. I/2). The map, compared in scale to the results of archaeological excavations and geophysical surveys shows an exact match with the currently known groundplan of the city wall, its northeastern corner and the amphitheatre. The third building may be identified as the centre of the provincial assembly (concilium provinciae)1 and the provincial imperial cult, namely the forum provinciae, that was situated within the territory of the Area sacra (Pl. I/1; Pl. II), approximately 20 metres to the northwest from the location given by Marsigli. The two textual fragments previously found in the area also support the assessment of the structure of forum provinciae. The dislocation of the third building on the map was presumably due to misprinting or Marsigli’s field error. Today, the area is still unexplored, only future archeological excavations can justify or refute the exact characteristics, structure and periodisation of the third building depicted on Marsigli’s map.

Tocra, the ancient Taucheira or Teucheira, in Cyrenaica was founded probably in the sixth century B.C. from Barce, to which it belonged in the time of Herodotus. Although it lies in what is now an easily accessible part of Cyrenaica, it has been very little visited by modern scholars. As is the case elsewhere in Cyrenaica, the outlines of the ancient city emerge distinctly from the ground even before excavation. The perfectly preserved circuit of the city walls goes back in origin perhaps to the fourth century B.C., but owes its present form to a reconstruction by Justinian after the defeat of the Vandals by Belisarius in A.D. 533. The stones for building the walls were taken from earlier buildings in the city, which thereby suffered much damage.

Abstract. Long-term urban extent data are highly desirable for understanding urban land use patterns and achieving sustainable development goals. However, urban observation data based on remote sensing are typically confined to recent decades. In this study, we advance in this arena by reconstructing the urban extents for China that extend back from 15th century to 19th century based on multiple historical documents. Cities in late imperial China (the Ming and the Qing Dynasties, 1368–1911) generally had city walls, and these walls were usually built around the urban built-up area. By restoring the scope of the city walls, the urban extend in this period could be restored. Firstly, we collected the years of construction or reconstruction of city walls from the historical data. Specifically, the period in which the scope of the city wall keeps unchanged is recorded as a lifetime of it. Secondly, specialization of the scope of the city wall could be conducted based on the urban morphology method, and variety of documentation, including the historical literature materials, the military topographic maps of the first half of the 20th century, and the remote sensing images of the 1970s. Correlation and integration of the lifetime and the spatial data would produce China City Wall Areas Dataset (CCWAD) in late imperial. Based on the proximity to the time of most of the city walls, we generated China Urban Extent Dataset (CUED) in the 15th–19th centuries in six representative years (i.e., 1400, 1537, 1648, 1708, 1787, and 1866). These datasets are available at https://doi.org/10.6084/m9.figshare.14112968.v1

Abstract. The ancient city wall is affected by factors such as environment and man-made factors, and the formed bulging disease is particularly prominent, and even caused irreversible damage to the ancient city wall. Therefore, the bulging monitoring after the repair of the city wall should be the top priority of the deformation monitoring of the city wall. This paper proposes a new plan for monitoring the bulge after the repair of the city wall. According to the point cloud data before the repair, the characteristic plane is fitted to determine the bulge range of the city wall, and then observation signs are placed on the surface of the repaired city wall at the corresponding location where the bulging deformation is severe. By using a total station to monitor the space coordinates of the observation signs, the deformations perpendicular to the wall can be obtained through coordinate conversion, and then the bulging of the repaired city wall can be determined. The actual application results show that this method can effectively monitor the swelling of the ancient city wall after the repair.
