Goesan Cheongan Anminheon is a government office building of Cheongan-hyeon from the Joseon Dynasty, said to have been built in the 5th year of King Taejong's reign (1405). It underwent several repairs, with the currently surviving structure believed to date from the late 19th century. Repairs were also done in 1915, and it was once used as the Cheongan branch office, resulting in some alterations, but it was restored in 1981. The building measures 6 kan at the front and 3 kan at the side, featuring a paljak-style roof with eaves shaped like the Korean character pal (八). It is a single-eave, single-bracket min-dori house built on a low stone foundation. The foundation stones include both dressed and natural stones, with round columns and some square columns. One kan at the front is an open wooden floor (toemaru), with the back left 3 kan forming the main hall (daecheong), the right 2 kan as ondol heated rooms, and the last 1 kan as a toemaru with a door.
The Cheongan Eupnae-ri Ginkgo Tree is a deciduous tree belonging to the ginkgo family, with a height of 17 meters and a trunk circumference of 7.1 meters at chest height. Its branches spread about 16 meters east-west and 15.5 meters north-south. The tree's age is estimated to be about 1,000 years. According to legend, during the reign of King Seongjong of Goryeo, the local lord was respected for his good governance by the people. One day, at a banquet for the villagers, he wished for a pond in the village, and the people dug a pond called 'Cheongdang.' The lord then planted many trees by the pond, and this ginkgo tree is the only surviving one. After the lord left for the royal court, the people composed poems to mourn and care for the noble lord. It is said that a snake with ears lives inside the tree, and anyone harming the tree will suffer harm from the snake within.
Cheongan Samaso was established in 1703 (the 29th year of King Sukjong of Joseon) when more than 50 students from Cheongan-hyeon passed the Samabang exam. It is presumed to have served as Sama-je, listing the names of those who passed the Saengwon-si at Cheongan Hyanggyo, those who passed the Jinsa exam in the preliminary stage, and scholars who passed the higher state exams. This Samaso recorded a total of 115 individuals: 8 from the literary exam, 40 Saengwon, 40 Jinsa, 3 notable figures, 2 eunuchs, and 22 landowners, performing rites twice a year in spring and autumn. It was abolished in 1910 during the Japanese colonial rule but was rebuilt by Confucian scholars of the Cheongan region in 1950 after liberation. The building is a wooden gable-roofed house with three bays front and two bays side. Samaso was established in towns with over 50 successful candidates in the Saengwon and Jinsa exams at Samabang; these successful candidates, respected local Confucians, held rituals, lectured on Confucianism, and discussed politics. Initially contributing to local development through fellowship, political discussions, and education, it later caused problems by interfering in local governance and unfairly punishing commoners. Currently, few Samasos remain as independent buildings, including Okju Samaso (Okcheon) and Gyeongju Samaso.
Cheongan Hyanggyo is a government education institution built in Cheongan during the early Joseon Dynasty to enshrine the spirit tablets of an outstanding Confucian scholar and to provide Confucian education and moral cultivation to local residents. The exact date of construction is unknown, but since a Samoso building was constructed in the 29th year of King Sukjong (1703), it is presumed that the Hyanggyo was built prior to that. The current buildings were dismantled and restored between 1979 and 1981. The Myeongnyundang, the lecture hall for study, is located in the front, and the Daeseongjeon, the space for ancestral rites, is situated in the rear, following the jeonhak-humyo layout. In Daeseongjeon, spirit tablets of Confucius as well as Chinese and Korean Confucian scholars are enshrined. The signboard of Myeongnyundang is said to have been written in the 9th year of King Yeongjo (1733). During the Joseon Dynasty, it was operated with land, slaves, and books provided by the state; however, the educational function has ceased, and now only the ritual function remains.
Seokbogun Myogak is a shrine house of the Jeonju Yi clan's Seokbogun branch located in Cheongan-myeon, Goesan-gun. It is an auxiliary shrine enshrining the spirit tablets of Seokbogun Yi Boksaeng, the 9th son of King Jeongjong of Joseon, his wife Wonju Kim, and Seokbogun's eldest son Yangwi. A sa-myo is a building where ancestral tablets or portraits are kept and rites performed, and a jae-sil is a building near graves or shrines used for preparing rites, including accommodations and ritual food for participants. Built as a thatched house in 1905, it was rebuilt with a tiled roof in 1930 and renovated in 1986. The complex consists of a Hongsalmun gate, three gates, and the auxiliary shrine. The shrine itself is a single-storied, double-eaved gable-roof building measuring three kan at the front and one and a half kan at the side. The floor plan features a front maru porch and an interior with a single room and a well floor. The foundation is a jangdae type with flat column bases; the front columns are round and the rear square. The bracket system is iikgong style, and the frame is one goju five-ryangga. The shrine’s dancheong uses moro dancheong, facing northwest. During renovation, modern red bricks on the side mid-beam and rear lower beam were removed and reconstructed using traditional methods. The jangmaru was replaced with a traditional onsik well floor. The beam joinery preserves traditional styles, and the walls and floor were restored closely to the original state. Designated a Chungcheongbuk-do cultural heritage site in 1996, it is managed by the Jeonju Yi clan, Seokbogun branch.
This main gate was originally built as the Jeongryeo of Jangdam in Cheongryong-ri, Cheongan-myeon, in the 5th year of King Yeongjo's reign (1729), and later relocated to Jocheon-ri. Jangdam's pen name was Supungjeong, and his bon-gwan (origin of clan) was Indong; he was a descendant of the Tongrye Jang In-gye. In the 4th year of King Yeongjo's reign, when Yi In-jae's rebellion broke out in Cheongju, Jangdam, a commoner without an official post, raised militia and died in the suppression of the rebellion. His younger brother Janghwan led the remaining troops to defeat the enemy and take revenge. Later, this deed was officially recognized, and he was enshrined as a loyal subject. He was awarded the title of Bunmuwonjong Hoon 1st grade, honored during King Jeongjo's reign with the title of Pyochung, and posthumously promoted to Left Seungji. The building is a wooden gabled roof structure with one bay in front and one bay on the side, featuring a name plaque and protective fencing.
