It features Wind Hill, Birdwatching Tower, Children's Adventure Playground, Urban Forest Park, Maze Park, and Flower Garden. Wind Hill has a small windmill that adds to the park's beauty. The Birdwatching Tower is equipped with telescopes for observing the birds and fish in the retention pond. The Children's Adventure Playground, created with direct involvement of children in its construction and supervision, contains unique play equipment rarely found nearby, making it an ideal space for children's activities. Various types of trees, including those in Maze Park, are planted to offer diverse sights to visitors.
This park offers a panoramic view of the Goseong-eup area and the South Sea. At the park entrance, there are neatly arranged monuments commemorating the deeds of sages. Climbing the 84 stairs leads to Bogwangsa, a branch temple of Okcheon Temple of the Jogye Order of Korean Buddhism. To the left of Bogwangsa, there are the Memorial Tower, Bonangak, and Korean War anti-communist monuments built to honor the spirits of patriotic martyrs. Along the mountain ridge above Bogwangsa, facilities for recreational sports and a magnolia rest area have been established, providing a perfect resting space for both exercise and relaxation, frequently used by the town residents. From here, a well-kept 3–4 meter wide walking trail extends over the ridge down to Sunam-ri and Sinwol-ri, a distance that can be covered in about one hour. Namsan Park is also renowned as a winter training site for professional track and field athletes. At the summit, an octagonal pavilion offers a sweeping view of Goseong Bay and Goseong-eup, making it a cozy and beautiful spot encouraging visitors to stay, promoting health and rest for the townspeople as well as those who climb the mountain.
Beogeum Shop is a place that discovers and utilizes objects that have undergone natural processing through human use and natural weathering. It carries out dual-purpose activities of protecting the marine environment and creating artworks through beachcombing (collecting or organizing trash discarded on the beach). Items that have become useless are given new roles through their hands. Colorful glass pieces picked up from sand or between stones are transformed into desirable items such as frames, souvenirs, and accessories like necklaces that brighten up your home. Visitors can also experience upcycling by drawing or writing on glass pieces to create magnets.
Goseong Hyanggyo was first established in 1398 and has played an important role in nurturing local talent and cultural development. The spaces of the hyanggyo are divided into two areas: education and rituals. Myeongnyundang, where Confucian students study, and Dongjae and Seojae, where they live daily, serve educational functions. Daeseongjeon and Dong, Seo-mu, which enshrine memorial tablets of Confucius and notable Confucian scholars, serve ritual functions. The building layout of Goseong Hyanggyo follows the typical hyanggyo linear style called jeonhakhu-myo, placing educational spaces in front and ritual spaces behind. The central axis linking Daeseongjeon, Naesammun, Myeongnyundang, and Pungwharu is straight, but Dongseomu and Seoseomu are unusually close to Daeseongjeon’s sides, Dongjae is on the east side of Myeongnyundang, and Seojae is partially adjacent to the west side, deviating from typical hyanggyo layouts. Unlike the usual linear form of Myeongnyundang, which embodies Confucian educational ideals, this Myeongnyundang has a rare ㄷ-shaped floor plan. The main gate, Pungwharu, serves as a leisure and summer teaching space for students and a reception area for guests.
The Goseong Songhakdong Burial Mounds are a cluster of about seven tombs from the Gaya period located in the Mugisan area north of Goseong-eup. Among them is Burial Mound No. 1, which resembles Japan's keyhole-shaped tumuli and has sparked heated debates between Korea and Japan. Since 1999, excavations by Dong-A University Museum have revealed key features of these burial mounds. All mounds have artificially compacted earthen embankments, with a technique of leveling hills and layering compacted earth. Burial Mound No. 1 consists of 17 stone cists and chambers combined into three independent round embankments, differing from Japanese keyhole tomb shapes. The B-1 stone chamber, the northernmost, differs from traditional Gaya tombs with red paint on the entrance, walls, and ceiling. Artifacts such as pottery, gilt-bronze earrings, horse gear, a large gilt-bronze decorative sword, a bronze goblet, and glass beads were found, indicating it as a tomb of a Sogaya king. The artifacts suggest these mounds date from the late 5th to early 6th centuries and served as central tombs for Sogaya's ruling elite or royal tombs. Goseong-gun, where the mounds are located, is known as the ancient site of Sogaya.
