History and Evolution
The history of Jeju City is deeply rooted in local mythology. The Samseonghyeol, three holes located in downtown Jeju, are revered as the place from which the three ancestors of the Jeju people are said to have emerged. During the period of Japanese rule, the area was renamed Saishū.
The modern landscape of the city has changed significantly since the 1970s. While thatched-roof buildings were once common, they are gradually being replaced by modern structures. A notable development is Shin Jeju (New Jeju), an area located up the hill from the airport that serves as a hub for many government buildings. In 2006, following a provincial vote, Jeju City was merged with Bukjeju County to create a larger administrative entity.

The city's central position in the island's transportation network makes it the primary entry point for millions of visitors from South Korea, Japan, and China.
