Bongju Jeongsa is the hanging wooden plaque of the namesake study hall in Gasan-ri, Changsu-myeon, Yeongdeok-gun. This plaque, measuring 123.5cm by 62.5cm, was donated by Lord Bongju lineage, Nam clan from Yeongnam. Bongju Jeongsa Study Hall was established to foster younger students by Nam Gukju (1690-1759, pen name Bongju) in 1724 (4th year of King Kyeongjong) and was recently relocated to the current site. The term ‘Bongju’ was taken from the pen name of Nam Gukju, which reflects his admiration for the beautiful landscape of nearby mountains (Bong) and rivers (Ju), where he enjoyed strolling and meditating in the morning and evening.
The study hall is enclosed with earth rock walls and the four-column gate on the front. It is composed of three rooms, with the wooden-floored hall in the middle and two rooms on its sides. There are two hanging wooden plaques hung at the hall in the middle, bearing the script ‘Bongju Jeongsa’, one written in the seal style and the other in the semi-cursive style. On the left side room is hung the plaque of ‘Bongju Jeongsa-gi’, meaning ‘Record of Bongju Jeongsa Study Hall’, written by Jang Seokyeong (pen name Hoedang). The wooden-floored hall has an extended wooden porch on the front and there hang two more plaques; ‘Geukbokjae’ under the left ceiling and ‘Kyeong-eui-dang’ under the right ceiling.
The calligraphy of this hanging wooden plaque is written in the square style by an unknown hand. While strokes are rough, the overall composition is well-organized, whose combination resembles the manners of a scholar who leads a leisurely life in nature but does not neglect his studies.
