Seuldo Island

Seuldo Island is located off the coast of Ulsan City in the southeastern part of the Korean Peninsula.

Its name, Seuldo ("seul" meaning the Korean stringed instrument geomungo), was given as the sound of wind and waves hitting the rock island is said to mimic the sound of geomungo. In fact, the sound of waves hitting the island is so good that it is called seuldomyeongpa or the resounding of waves.

The island is also known as Siruseom ("siru" meaning an earthenare steamer) for its resemblance to the upside down siru, and Gomboseom ("gombo" meaning pockmarks) for its stones with holes in them.

On the island, there is an unmanned lighthouse dating back to the late 1950s. The main economic activity on the island is fishery.
