The photo taken on March 23, 2003 shows a section of the "Great Wall Under Water", which emerges out of the Panjiakou Reservoir in Kuancheng Manchu Autonomous County, north China's Hebei Province. The Xifengkou and Panjiakou Great Wall built in ancient China's Ming Dynasty (1368-1644) lied in the water following the building of the Panjiakou Reservoir in 1979. But sharp drop of the reservoir's water level because of drought brought it above the water at the end of the 20th century. Recently, parts of the Great Wall, which emerged out of the water, were submerged again due to the ecological improvements and sufficient rainfall. (Xinhua)
