A lost section of the Great Wall of China has recently re-emerged after spending several decades hidden under water.
Drought and increased hydrological activities made water levels decline significantly in the Panjiakou Reservoir located in Kuancheng Man Autonomous County, Hebei Province, northern China.
The reservoir was created in 1978 with the aim of providing water to the cities of Tianjin and Tangshan, which are located south. However, before the reservoir came into function, an extensive section of the Great Wall of China ran along the surrounding hills and through the passage of Panjiakou. In fact, a small part of the defensive monument located on the edge of the reservoir emerges when water levels decline during droughts, becoming a temporary tourist attraction.
Now, partly because of the excessive agriculture and industrial activity, water levels have decreased exposing an entire section of the historic defensive wall. Local news agencies have said that even the towers that disrupt the walls are still intact.
The structure was built during the Ming Dynasty more than 500 years ago as a massive defense system. The part of the wall that once passed near Panjiakou ran along a stronghold of the region and another one located in Xiafeng.
However, when the Chinese began the construction of the dam in the 1970s, the area was submerged under 644.510 million gallons of water. Likewise, the town of Panjiakou was covered by 50 meters of water. Ever since that part of the Great Wall sank, the site has become an attraction to divers who visit the reservoir to explore the sunken section of the Great Wall of China.
However, when the current drought hitting the province ends, it is very likely that this section of the great wall of China will once again disappear beneath the water, becoming once again, a tourist attraction for divers around the world.
The Great Wall of China is considered the worlds largest man-made structure and is believed to be 13,170 miles long. It was constructed over a period of 1,000 years. The building process began during the Qin dynasty as part of a new defensive line in hopes of stoping enemies from the north.
Larger parts of the wall were constructed during the Ming dynast, and helped protect against the Mongolian tribes. Interestingly, this section of the great wall is the most visited today.
