Ryongam Cavern is located in Kujang County, North Pyongan Province, and is one of the most significant limestone cave systems in North Korea. Extending for several kilometers, the cavern is renowned for its extraordinary dripstone formations, including stalactites, stalagmites, and massive stone pillars. These formations were created over hundreds of thousands of years through the chemical weathering of limestone by carbonated seepage water. Geologically, the cave belongs to an extensive karst region deposited during the Paleozoic era. Inside the cavern, there are several underground chambers and rivers that maintain a constant annual temperature of about 12 degrees Celsius. Historically, the cave was used as a shelter during various conflicts, while today it is primarily protected as a natural monument. Ryongam Cavern hosts specialized fauna, including rare bat species and blind cave insects adapted to absolute darkness. Scientific research into the cave system provides valuable data on paleoclimatology and the geological history of Korea's northwestern coastal region.
