Simatai Great Wall Building - single-sided wall

Walking from the fourth floor, you can see a stone single-sided wall less than 100 meters high. This wall is about 3 meters high, and two rows of brick perforations are arranged on the wall. It is particularly worth mentioning that the cover brick on the eaves of the perforated inner opening is 57 cm long, which is the largest brick found in this section of the Great Wall. It demonstrates the level of brick firing by military industry. The single-sided wall is another architectural feature of Simatai Great Wall presented in multiple forms. There are dozens of meters of brick (similar to parapet) single-sided walls to the east of the 12th floor, and about 300 meters of stone single-sided walls capped by Great Wall bricks (in some sections) from the 15th floor (Fairy Tower) to the 16th floor (Wangjing Tower), without arrow holes, which are called "flyover" by locals. It should be said that when the ancestors built Simatai Great Wall, they consciously preserved the architectural forms of the important trimming periods of Ming Dynasty. For example, the camp city built during the Hongwu period of the Ming Dynasty (1373 to the construction of pass and fortress), the single-sided wall built during the Chenghua period (1465-1487), the barrier wall and wall-attached platform built during the Jiajing period (1545-1550), the city wall built in the third year of Qin Long (AD 1569) to the middle Wanli period (AD 1587) and various hollow beacon towers, so that future generations have the opportunity to enjoy their architectural style, so some people also call this Great Wall a natural "Great Wall Museum", which is visually enjoyable and has high research value.
