Three Brothers Cave Rock, towering approximately 44 meters high, is situated between the East Island and West Island of Dokdo. This geological formation is a result of volcanic activity; its lower section emerged from cooling lava following an eruption, while its upper part was shaped by the accumulation of volcanic ash. Over time, the relentless action of waves has sculpted the rock, forming caves in three different directions. This unique structure, resembling three pillars converging in mid-air, is the inspiration behind its name, Three Brothers Cave Rock.
