Cheonan
Cheonan has always been a major transportation hub of Korea because of its proximity to Seoul and its location near a gap in the eastern mountain range () that allows passage through to the major southeast centers of Daegu and Busan. Cheonan’s Samgeori (meaning “3 way intersection”) park has been noted as a strategic point of transportation and a place where culture has spread for a long time. It is the place where Samnamdaero, which starts in Seoul, parts, leading one branch of the road through to the south-eastern Yeongnam region (which includes Gimcheon, Daegu, Gyeongju and Dongnae), and leading the other through Gongju and Nonsan to the Honam region (which includes Jeonju, Gwangju, Suncheon, and Yeosu).
