he Cheju Island area around the Port of Jeju was important before history was first recorded. In the central Port of Jeju are the Samseonghyeol, three holes from which legend says came three old families (the Samseong-Ko, Pu, and Yang), the ancestors of the Jeju people. The political, commercial, and cultural centre of the island since it was an independent kingdom in ancient times, the Port of Jeju developed as a seaport after 1913.
