Where the Earth’s Pulse Beats, The Prologue of the Yangnam Columnar Joint Group


The Gyeongju Yangnam Columnar Joint Observatory was built in October 2017 to provide the most three-dimensional and beautiful view of the Yangnam Columnar Joint Group, which has been designated a National Geopark. The Columnar Joint Group, which developed extensively along the coastline of Eupcheon-ri, Yangnam-myeon, Gyeongju, is a masterpiece of nature created over a long period by the combination of waves, wind, and tectonic activity. The moment you set foot here, you will feel as if you have arrived on another planet.
As its name, Observatory, suggests, this place offers an experience beyond mere viewing. It is a space where you can encounter not only the magnificent columnar joint panorama unfolding through the wide-open view but also diverse geological stories hidden within it.
Only Here: The Mysterious Form of Fan-shaped Columnar Joints



The reason the Yangnam Columnar Joint Group is special lies in the diversity of its forms. Not only are there pillar-like forms rising upward, but also various mixed forms that demonstrate nature’s unpredictable beauty.
- Upright Columnar Joints: Hexagonal pillars extending straight towards the sky create a spectacular sight.
- Tilted Columnar Joints: Their unique, flowing appearance, tilted diagonally, captures the eye.
- Recumbent Columnar Joints: Exposed by the waves, they lie spread out along the coast as if resting.
Among all these forms, the absolute highlight is the ‘fan-shaped columnar joints’. These columnar joints, extending circularly as if a giant fan has been spread open, are so rare that they are difficult to find anywhere else in the world, and their geological value was recognized, leading to their designation as a Natural Monument in September 2012. At the Gyeongju Yangnam Columnar Joint Observatory, admire this rare artwork of nature up close and feel its mysterious energy with your whole body.
