Guguan Great Wall is located in Xinguan Village, Pingding County, Shanxi Province, on the west side of Taihang Mountain. It is an important pass of the Great Wall in the north, from Niangziguan Jiayugou, to the south to the entrance of Baihui Village. Guguan Great Wall is the only existing stone wall that can be considered in China's earliest Ming Dynasty, and the famous Great Wall expert Luo Zhewen called it "the charm of a small Badaling".
