At that time, Truong Phu (a general in the Ming Dynasty - China) after conquering our country and imposing colonial rule, strengthened the organization of the political apparatus in the area. Legend has it that during this time he built Khau On citadel. Regarding the construction of Doan Thanh, there is another legend that the Citadel was built by two fairies who came down to help build it. Perhaps that is why the Ancient Citadel also has another name, "Citadel built by Tien". According to Dai Nam Nhat Thong Chi: "... In the 26th year of Hong Duc's reign, the Le Dynasty (1495) citadel was restored...". Based on some of the documents mentioned above, it can be predicted that Lang Son Citadel was built during the Ly or Tran dynasties around the 12th and 13th centuries. The citadel was built on wide and flat terrain, covering a large space of Lang Son city (formerly known as Thanh Lang). Surrounding the citadel are mountains and Ky Cung river flowing through. Those mountains are also called Hoi Doan mountain (north), and Cong Mau mountain in the south. The architecture of Doan Thanh is like other ancient citadels with high walls and deep moat... (the moat here is the winding Ky Cung river). Surrounded by checkpoints located in communes and continents near and far, there are a total of 19 checkpoints, 3 checkpoints and 26 checkpoints. The citadel's walls were built of "mound bricks", a type of large-sized ancient brick, the 4m high vertical wall is very difficult to penetrate and attack from the outside, however, there was a time "... Doan Thanh was attacked three times. fell, the people of seven continents were forced into a miserable situation. The inner western and southern walls of the citadel were covered with soil up to the citadel's surface, at the base of the citadel was a 10m wide soil embankment, on the citadel surface was a 3m wide soil embankment, very convenient. beneficial for the majority of soldiers participating in combat. The height of the inner earth wall is equal to the height of the outer wall, forming a sturdy square trapezoid with a gentle slope that is very convenient for deploying soldiers to the surface. Citadel, in the southwest corner where the western and southern walls meet, there is a small earthen mountain called To Son. The inner eastern and northern walls are not covered with earth, but on the surface of the wall there are pearl holes. apricot; On top of the brick citadel wall, brick walls were built projecting on both sides, each side 0.1m to form a durable roof to protect the citadel wall. The ancient citadel currently has two remaining gates (one gate in the West and one gate in the South). , the city gate was designed and built in the Van Ban (Vo Bang) architectural style of France. Doan Thanh is not only located on rugged terrain, it is also considered sacred land. According to folk legend, this is also the meeting place of Princess Lieu Hanh (Holy Mother) and Trang Bung - Phung Khac Khoan. The ancient citadel was a major military, political, economic and cultural center of Lang Son during the feudal period. Besides, the Ancient Citadel also clearly demonstrates its important role and position in the matter of relations with the Northern feudal dynasties. This is the border crossing point, the place of communication between the two countries Dai Viet - China. The ancient citadel has 4 main gates in the four directions East, West, South, North and corresponding to these 4 gates are 4 sacred temples called: Dong Mon Tu, Tay Mon Tu, Nam Mon Tu, Bac Mon Tu (now called are: East Cua Temple, West Cua Temple, South Cua Temple, North Cua Temple) those are the four gods guarding the four sides of Doan Thanh.
