Ryongmun Cavern, a renowned underground scenic spot located at the foot of Mt Ryongmun (1 180 metres above sea level) in Kujang County of North Phyongan Province, was formed 480 million years ago.
Comprised of two major sections and 30-odd wings, it has a total length of 7.2 kilometres, being the largest one in the DPRK.
Ryongmun Plaza, the largest part of the cavern, covers 3 600 square metres in area.
The cavern has over 20 spots for spectacular and fantastic scenery, including Manmuldong (myriad-shape section), Phungnyondong (bumper harvest section), Sokhwadong (stone flower section), Posokdong (jewel section), and Kumgang Palace, and also many other shapes resembling human figures and bodily organs, plants and animals. Such views are presented by stalactites and stalagmites developed through the centuries-long process of erosion of the limestone by underground water.
Anybody who wants to tour the cavern can use the Pyongyang-Kujang, Sinuiju-Kujang and other road lines.
