Seosan, South Chungcheong, Chungcheong Region, South Korea

🇰🇷 Seosan is a city in South Chungcheong Province, South Korea. Located at the north-western end of South Chungcheong Province, it is bounded by Dangjin City, Naepo New Town, Yesan-gun and Hongseong-gun on the east and by Taean-gun and the Yellow Sea on the west, and is 125 km (78 mi) south of Seoul, 159 km (99 mi) north-west of Daejeon and 34 km (21 mi) north-west of Naepo New Town. Seosan is the hub of transportation of the west coast where the Seohaean Expressway, Daejeon-Dangjin Expressway, 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.

Haemieupseong Fortress (해미읍성) Located in Haemi-eup, approximately 12 km (7.5 mi) from Seosan (15 minutes by car or local bus; 45 minutes by bike), Haemieupseong Fortress is among the best preserved examples of Korea's Joseon-era fortress architecture, and unlike most Joseon-era fortifications, it was built on a flat plain rather than on a hill or mountain. Haemieupseong Fortress was completed in 1491 (22nd year of King Seongjong's reign), and surrounded the entirety of Haemi-eup at the time of its completion. The fortress was used as a military command post controlling the Chuncheong-do region, and provided defense against Japanese pirates along Korea's western coast. As the town of Haemi expanded in the early 20th century, much of the fortress was torn down to allow additional urban development, but a major restoration work was undertaken in 1973. Today, the South Gate of Haemieupseong Fortress is original, along with certain parts of the walls, while the other gates are reconstructions. Along with Yeosutgol, Haemieupseong Fortress is considered to be a Holy Ground among Korean Catholics due to the Byeongin Persecutions of 1866, during which many Catholics living in the Chuncheong area were killed at the fortress.

Yeosutgol Holy Ground (해미순교성지) Approximately 200 meters from Haemieupseong Fortress is the Yeosutgol Holy Ground, where Korean Catholics were buried alive, drowned and otherwise killed en masse during the Byeongin Persecutions. Although most of the site's remains were washed away by flooding, some of them were rediscovered in 1935. The site now contains a large memorial hall devoted to those who were martyred for their faith, and is now a major Catholic pilgrimage site.

Yeonghyeon-ri Rock-carved Buddha Triad (용현리 마애여래삼존상) During the Three Kingdoms Period (~ 57 BCE - 668 CE), the Seosan-Haemi area was under the control of the Kingdom of Baekje (백제), and although there are very few ruins from this period in the Seosan-Haemi area, the Yeonghyeon-ri Rock-carved Buddha triad is a phenomenal exception. Carved in either the late 6th or early 7th century CE, the carving consists of a Buddha standing on a lotus leaf, flanked by two Bodhisattva. Although this carving has been designated a National Treasure of Korea, it receives relatively few visitors due to its isolation. The carving is best viewed in the morning, when the entirety of the triad is illuminated by the rising sun, and is accessible by local buses from Seosan and Unsan-ri, or by a half-hour drive or ninety-minute bike ride directly from Seosan.

Bowonsa (보원사지) Built during the Unified Silla Period (668 - 935 CE), this small temple contains an iconic Baekje-style Pagoda, as well as a number of monuments which were added when the temple was expanded during the Goryeo Dynasty (918 - 1392 CE), and is considered to be a National Treasure of Korea. Bowonsa is about 500 meters from the Yeonghyeon-ri Rock-carved Buddha Triad, and is a quiet place for relaxation and meditation.

Gaesimsa (개심사) Built in 1484 (15th year of King Seongjong's reign), Gaesimsa is one of only a handful of wooden buildings in Korea which date past the 17th century. The temple houses an Amitabha Buddha statue carved in the 14th century, as well as a hanging mural painted in the 15th century, both of which have won Gaesimsa the title of National Treasure of Korea. At the temple's rear is a mountain path which links to the Aramegil Hiking Trails, and can be used to reach Bowonsa and Yeonghyeon-ri on foot within a 90-120 minute hike.
