Seoul, officially the Seoul Special City, is the capital and largest city of South Korea. A megacity with a population of over 10 million, it is one of the largest cities in the world. The Seoul National Capital Area is the world’s second largest metropolitan area with over 24.5 million inhabitants, which includes the Incheon metropolis and most of Gyeonggi province. Almost half of South Korea’s population live in the Seoul National Capital Area, and nearly a quarter in Seoul itself, making it the country’s foremost economic, political, and cultural center.
Seoul has been a major settlement for over 2,000 years, with its foundation dating back to 18 B.C. when Baekje, one of the Three Kingdoms of Korea, established its capital in what is now south-east Seoul. It continued as the capital of Korea during the Joseon Dynasty and the Korean Empire.
The Seoul National Capital Area is home to four UNESCO World Heritage Sites: Changdeokgung, Hwaseong Fortress, Jongmyo Shrine and the Royal Tombs of the Joseon Dynasty.
Today, Seoul is considered to be a leading global city, ranking among the top ten global cities in the Global Cities Index of 2010. It is one of the world’s top ten financial and commercial centers, home to major multinational conglomerates such as Samsung, LG and Hyundai-Kia. In 2008, Seoul was named the world’s sixth most economically powerful city by Forbes.
Seoul has a highly technologically advanced infrastructure. Its Digital Media City is the world’s first complex for IT and multimedia applications. Seoul was the first city to feature DMB, a digital mobile TV technology and WiBro, a wireless high-speed mobile internet service. It has a fast, high-penetration 100 Mbit/s fibre-optic broadband network, which is being upgraded to 1 Gbit/s by 2012. Seoul Station houses the 350 km/h KTX bullet train and the Seoul Subway is the third largest in the world, with over 200 million passengers every year. Seoul is connected via AREX to Incheon International Airport, rated as the best airport in the world by Airports Council International.
Seoul hosted the 1988 Summer Olympics, 2002 FIFA World Cup and the 2010 G-20 Seoul summit. The city was named the World Design Capital for 2010 by the International Council of Societies of Industrial Design.
Seoul is in the northwest of South Korea. Seoul proper comprises 605.25 km², with a radius of approximately 15 km, roughly bisected into northern and southern halves by the Han River. The Han River and its surrounding area played an important role in Korean history. The Three Kingdoms of Korea strove to take control of this land, where the river was used as a trade route to China (via the Yellow Sea). The river is no longer actively used for navigation, because its estuary is located at the borders of the two Koreas, with civilian entry barred. The city is bordered by eight mountains, as well as the more level lands of the Han River plain and western areas.
Seoul lies in the border region between a humid subtropical and humid continental climate, depending on the definition. Summers are generally hot and humid, with the East Asian monsoon taking place from June until July. August, the warmest month, has an average temperature of 22.1 to 29.5 °C (72 to 85 °F) with higher temperatures possible. Winters are often relatively cold with an average January temperature of -6.1 to 1.6 °C (21 to 34.9 °F) and are generally much drier than summers, with an average of 28 days of snow annually.
Major modern landmarks in Seoul include the Korea Finance Building, N Seoul Tower, the World Trade Center and the seven-skyscraper residence Tower Palace. These and various high-rise office buildings, like the Seoul Star Tower and Jongno Tower, dominate the city’s skyline. Due to its high density, Seoul has a vast array of skyscrapers; the city council is now planning a series of new highrises, including a 640-meter business center in Sangam Digital Media City district and the 523-meter Lotte World 2 Tower in the Jamsil (pronounced “Jam-shil”) district of Songpa-gu and Gangdong-gu.
The World Trade Center of Korea, located in Gangnam-gu, hosts various expositions and conferences. Also in Gangnam-gu is the COEX Mall, a large indoor shopping and entertainment complex. Downstream from Gangnam-gu is Yeouido, a island that is home to the National Assembly, major broadcasting studios, and a number of large office buildings, as well as the Korea Finance Building and the world’s largest Pentecostal church. The Olympic Stadium, Olympic Park, and Lotte World are located in Songpa-gu, on the south side of the Han River, upstream from Gangnam-gu.
In 2011, the Dongdaemun Design Plaza & Park, designed by Zaha Hadid, is scheduled to open. This will coincide with Seoul’s designation as World Design Capital that year.
