Huanghuacheng Great Wall is not only more beautiful, but also much less tourists than tourists site. It was a strategic military pass to defend the imperial tombs in the Ming Dynasty(1368-1644). The Wall was built on the ridge of the mountains, and both stone and

bricks were employed on the construction. In early 1950s the local authority set up two dam sites for irrigation and flood control and parts of the Wall submerged into the water. You will see two reservoirs at the beginning and the end of the hike. Huanghuacheng played an important role to protect the imperlal capital and mausoleums in the Ming Dynasty. In order to defend the capital and imperial tombs, two types of the Wall were built to the north of Beijing, Outer Great Wall and Inner Great Wall. Huanghuacheng is a part of the Inner Great Wall.
