FUN FACTS
Daejeon (Korean: 대전; Korean: [tɛdʑʌn] ) is South Korea's fifth-largest metropolis, with a population of nearly 1.5 million.
Located in a central lowland valley between the Sobaek Mountains and the Geum River, the city is known both as a technology and research center, and for its close relationship with the natural environment.
Daejeon is a major transportation hub, having grown up as a railway town, and is approximately 50 minutes from the capital, Seoul, by KTX or SRT high speed rail.
From the 1980s, multiple national administrative functions were moved from Seoul to Daejeon, most of which are now located in the Daejeon Government Complex, resulting in another population increase.
Daejeon is situated in a lowland valley with three major rivers, all of them eventually flowing into the Yellow Sea by way of the Geum river.
