Gubeikou Great WallⅡ
The first section of the wall was built during the Northern Qi Dynasty (550 - 557). Centuries later, General Xuda ordered to rebuild it in the early Ming Dynasty (1368 - 1644). The defensive capability of the wall was enhanced by adding more stones. When Qi Jiguang was appointed the chief commanding officer of Ji Garrison (one of the eleven garrisons in Ming Dynasty), he laid another line of brick wall beside the original one, thus forming the unique Gubeikou double-lined Wall.
Although the battle smell of Gubeikou Great Wall has been faded out, people also can find the marks in the history. With a length about 25 miles, Gubeikou Great Wall takes 14 beacon towers, 143 watch towers, 16 strategic pass, three citadels and many other military constructions. These cultural relics such as the Big Flower Beacon, Tower of the Northern Qi Dynasty and the dominant Wangjing Tower still tell the past stories to the world quietly.
