Seosan

Seosan (; ) is a city in South Chungcheong Province, South Korea, with a population of roughly 175,000 according to the 2017 census. Located at the northwestern end of South Chungcheong Province, it is bounded by Dangjin, Naepo New Town, Yesan-gun and Hongseong-gun on the east, Taean-gun and the Yellow Sea on the west, south of Seoul, northwest of Daejeon and northwest of Naepo New Town. Seosan is the hub of transportation on the west coast where the Seohaean Expressway, Daejeon-Dangjin Expressway, and National Highways No. 29, 32, 38, and 45 intersect.

== Culture and tourism == Although Seosan itself is fairly quiet and attracts relatively few tourists, there are a number of minor attractions in the rural areas outside of Seosan, most of which can be accessed within twenty minutes by car, or in an hour by bicycle. Many of these historic sites are well-known only among the locals and often have few visitors, which can make them appealing to those wishing to escape the crowded palaces and temples of Korea's major cities. For an exhaustive list of tourist attractions in the Seosan-Haemi area, detailed English-language maps are available at the Seosan Intercity Bus Terminal.
