Badaling Great Wall, with more than 1000 meters above sea level, occupies a commanding and strategic position. It is a defensive outpost of the Great Wall. It is called "Bada" as it stretches in all directions.
Badaling Great wall was built in the 18th year of the Ming Hong Zhi reign (1505). The wall, built with high stone slabs on the outside, is 7.8 meters high on the average, some even reaches 8.4meters. The base of the wall was built with more than 2000 large rectangular slab of granite stones. It is about 6.5 meters wide on the average at its base and 5.7 meters wide on the average on the ramparts. The wall is wide enough for five horses to gallop abreast and ten people to advance shoulder to shoulder. The outside of the wall is called rampart wall. The rampart wall was built with bricks 1.7 meters high. Built for the purpose of defense, there are holes on the tip of the wall called watch-hole, and peepholes under the wall called embrasures. Inside of the wall, there are low walls with one meter high called parapets, which can be used as railings. There is a scroll door not far from the inside wall, with is a stone ladder for climbing up and down.
The wall is narrow on the top and broad on the bottom forming an adder-shape structure. This made the wall stands firmly on the rise and fall ridges. The wall was built with 10-14 rectangular slab of stones surrounding its outside, filled with soilsand stones in the middle, and paved with square bricks on the top between the bricks were stuck with lime stones. This makes the wall tidy, beautiful, and firm. There are gutters with gargoyles to drain rain-water off the parapet wall.
