Seoul

Seoul is the capital and largest city of South Korea. With over ten million people, and 23 million in the wider metropolitan area, Seoul is one of the world's largest cities proper and metropolitan cities. As a Special City, it is administered directly by the national government.

The city is located on the basin of the Han River in the country's northwest. The North Korean border is about 50 km to the north.

Seoul first appears in history in 18 BC, when the Baekje kingdom established its capital Wiryeseong in what is now around Songpa-gu, southeastern Seoul. Modern Seoul descends from the Goryeo-era city called Namgyeong, which then became the capital of Korea during the Joseon dynasty.

The Seoul National Capital Area - which includes the major port city of Incheon and many satellite towns in Gyeonggi-do - has almost 23 million inhabitants, making it the second most populous metropolitan area in the world. Almost half of South Korea's population lives in the Seoul National Capital Area, and nearly one quarter in Seoul itself, making it the country's political, cultural, and economic centre. As of 2007, Seoul became the third most expensive city in the world and the most expensive in Asia

In recent years, the metropolitan government has undertaken major environmental projects, including the restoration of Cheonggyecheon.

The city has been known in the past by the successive names Wirye-seong (위례성; 慰禮城, Baekje era), Namgyeong (남경; 南京, Goryeo era), Hanseong (한성; 漢城, Joseon era), and Hanyang (한양; 漢陽). Its current name,Seoul originated from the Korean word "seo'ul" meaning "capital city". It is presumed that the origin of the native word "seo'ul" derives from the native name Seorabeol (서라벌; 徐羅伐), which originally referred to Gyeongju, the capital of Silla.

Unlike most place names in Korea, "Seoul" has no corresponding hanja (Chinese characters used in the Korean language). The Chinese name for Seoul is 首爾 ("Shǒu'ěr" in Chinese pronunciation).

The history of Seoul can be traced back as far as 18 BC, when it was established as a settlement in Baekje. It's believed that the Wiryeseong site is in the boundaries of modern day Seoul. It has thereafter been the capital of the Joseon Dynasty. In the Japanese colonization period in the early 20th century, many historical and traditional parts of Seoul were changed. The city was almost entirely destroyed in the Korean War, but an aggressive economic policy in the 1960s and 1970s helped to rebuild the city very rapidly. In the 1990s, some important historical buildings were restored, including Gyeongbokgung, one of the royal palaces of the Joseon dynasty.
