Ocheon Port was a center of trade with the Tang Dynasty during the United Silla period. As Japanese pirates often appeared around the port area during the Goryeo Dynasty, Ocheonseong (fortress) was built as a lookout to the sea. During the Joseon Dynasty, the military base of Chungcheong Sugun Jeoldosa (naval commander-in- chief) was constructed in Ocheon. Presently, Manghwamun (the north gate), Jinhyulcheong where the poor were well cared for, a military camp for officers, and a fortress still remain.
Nampo Eupseong (fortress) which was constructed during the Joseon Dynasty has been well preserved. Nampo- hyeon government buildings such as Jinseoru, Oksanamun, and Dongheon have been well preserved also.
Since 1974, the Tomb of General Jwa-Jin Kim (a commander of the Korean Independence Army) has been sacredly preserved. In order to pass down his achievement and spirit of independence to future generations, a date for a sacrificial offering was set for October 22 when the Cheongsan-ri Battle ended in victory. Every year, many celebrities visit this tomb and pay tribute to the General’s achievement and integrity.
Boryeong Fortress was constructed during the Goryeo Dynasty and remodeled from a mud castle to a stone fortress during the Joseon period. A tablet called “Haesanru” at the entrance was written by San-Hae Lee who was a prime minister of the Joseon Dynasty during the reign of King Seonjo.
