Ulsan

Ulsan (Korean: 울산), officially Ulsan Metropolitan City, is a major city in southeastern South Korea, with a population exceeding 1.1 million, making it the nation’s seventh-largest metropolitan city and eighth-largest overall. It borders Busan to the south and faces Gyeongju to the north. The city is the heart of the Ulsan Industrial District and serves as South Korea’s industrial powerhouse. It hosts the world’s largest automobile assembly plant, operated by Hyundai Motor Company; the world’s largest shipyard, run by Hyundai Heavy Industries; and the world’s third-largest oil refinery, owned by SK Energy. In 2020, Ulsan recorded a GDP per capita of $65,352, the highest of any region in South Korea.

Historically, stone tools from the Mugeo-dong Ok-hyeon site show human habitation as early as the Paleolithic era, with further evidence from the Neolithic and Bronze Ages. During the Jinhan confederacy, the area was a center for iron mining and production. In the Later Silla period, Ulsan served as a key port for the economic hub of Gyeongju, likely importing luxury goods such as Persian silver, glass, and peacock tails. In 1592, it was the site of a major battle where warrior monks and citizen soldiers resisted Japanese invasion; a combined Korean-Chinese siege of a castle in 1598 failed due to Japanese reinforcements. By 1642, during the Joseon period, Ulsan was developed as a shipbuilding site. The city grew as an industrial center during the two World Wars while part of Keishōnan-dō. In 1962, it was designated a Special Industrial Zone, becoming a city the following year. Hyundai and SK groups established large operations, including the shipyard and automobile plant, transforming Ulsan into a modern metropolis. It was promoted to a metropolitan city on July 15, 1997.

Ulsan is located at the southeastern tip of the Korean Peninsula, at the southern end of the Taebaek Mountains, with a mountainous emergent coastline along the East Sea. The Taehwa River flows through the city, and its ecological restoration has been a focus since the early 21st century. The climate is monsoon-influenced humid subtropical, with cold, dry winters and hot, humid summers. According to the 2015 census, most residents reported no religious affiliation; Buddhism was the largest religion (29.8%), followed by Protestantism (10.9%) and Roman Catholicism (4.2%).
