You can be informed and join the various events because there are many other selectable special interesting events as well as the annual celebration.

Oseong Cultural Festival which has been held since 1992 is the event to pay tribute to the memory of five faithful old men who were killed by the Sojeongbang, a commander of 130,000 Tang soldiers, for they had refused to show the way to Sabiseong saying "we won't show the way to the invader of our country" at that time the allied force of Shilla-Tang invaded Baekje in the 20th year of King Euija in Baekje (660). In every early October, the memorial service in Confucian ritual is held in front of Tomb of the Five Sages on the top of the Mt. Oseong in which rises 227 meter above the sea level and commands fine prospect of Geumkang River. There are many assorted culture and art events including Samulnori (tradition percussion quartet) and Pansori (traditional long epic song) for few days all over the place in the area.

Under the influence of Gunsan's geographical location combining the inland and islands, Yongwang Gut (exorcism) has been prevalent for a long time to pray for the safety of those who travel the sea and a good haul, which the hereditary shamans pacify the Yongwang (Dragon God) with delightful performance of both song and dance.
In old days, Yongwang Gut was frequently held in every early June and July in lunar calendar, as there were many hereditary shamans. But it has been hardly held since 1960, apart from the Yongwang Gut that has been specially arranged by ship owners.
The Yongwang Gut of this area combines the features of both inland and island, which has something to do with the geographical condition of Gunsan. Yongwang Gut in inland only prays for the safety at the river or stream while that in island mainly prays for a good haul by pacifying the spirit of those who were drowned in the sea.
Yongwang Gut consists of seven episodes: Yongwangkangshin Gut ?’Bujeong Gut ?’Yukaphaeweonpuri Gut ?’Seonwangpuri Gut ??Jungcheonhaewon Gut ?’Kiweon Gut ?’Yongwangsajapuri Gut. Five or six shamans sang a song and played instruments including Jangko, Jing, Ajeng and Danso by turns from morning to night.
Although the control power of shamans was divided into two areas: east and west, Yongwang Gut was unique joint event for two groups of shaman. When shamans fixed a date, ship owners, fish dealers and fishermen contributed their offering such as rice, fruits and cotton cloth. Under a marquee fixed towards the Gogunsan, Yongwang Gut started from Daejabi Gut that invited the God of Mt. Weolmyeong.
Based on the historical point of view, Park Sun-Ho, a professor of Weonkwang University, and Lee Byeong-Hun, a former director of the Gunsan Cultural Center, restored the Yongwang Gut that had been hardly kept alive as a modified form combined with the Buddhist civilization in the process of modernization. The restored Yongwang Gut seems to talk with Gods of both mountain and sea to pray for escaping a disaster.

It is a representative festival held in celebration of Children's Day which invites internal and external juvenile dramatic companies to provide a variety of interesting events that everybody from children to seniors and all the families can enjoy.

Comprehensive Art Festival started from the art festival held in celebration of founding Gunsan branch of Korea Federation of Culture & Art Organization in 1969. In every October, 8-affiliated organizations participate in the variegated functions, making a contribution to improve the civic cultural life and promote the art activities of the area.

It is the festival to make citizens, merchants, and tourists join in harmony and offer the performances and the events based on seafood that they can see, taste, experience, and enjoy themselves. It shows the special quality of Gunsan which has the largest dried fish market in the country.
