Gyeongbuk Donghaean UNESCO Global Geopark
Celebrating Earth Heritage
Gyeongbuk Donghaean UNESCO Global Geopark, located along the southeastern coast of Gyeongsangbuk-do, contains a wealth of geological wonders, including the spectacular Deokgu Valley with its ancient granitic rocks and hot springs. The spectacular Seongryugul Limestone Cave stretches 870 meters and is adorned with stalagmites, preserving valuable evidence of past sea levels and ancient marine environments. Among the geopark’s most celebrated and beloved sites are the Yangnam Columnar Joints. These striking rock formations were created when volcanic lava cooled and contracted, with the site showcasing rare radial and fan-shaped patterns that lie horizontally to the ground. They have become a symbol of local pride for the geopark. Lee Chang-woon, a baker from Gyeongju, created the “Yangnam Columnar Joint Bread” made with local ingredients, linking the area’s geological heritage with the community.
