It was designated as Gyeongsangnam-do Tangible Cultural Heritage No. 158 on December 20, 1976.
It is located at the border between Gaya and Haman, 3 km west of Gaya-eup,
where Mujin(無盡) Josam(趙參), a civil official of the Joseon Dynasty, lived.
In 1567 (the 22nd year of King Myeongjong's reign),
his descendants built a pavilion near the pond to commemorate his virtue and named it Mujinjeong.
The Pyeonaek and Jeonggi called 'Mujinjeong' are presumed to have been written by Ju Se-bung.
The current building, which was reconstructed in April 1929,
is a simple and simple hipped-and-gabled building with no decorations or sculptures on top of the pillars,
showing the pavilion style of the early Joseon Dynasty.
It is composed of 3 bays in front space and 2 bays in side space,
and the front and back sides are elongated and one of the rooms in the center is decorated with ondol rooms.
Mujin passed the state examination(國子監試) in 1483 (the 14th year of King Seongjong's reign)
and passed the state examination in 1507 (the 2nd year of King Jungjong's reign),
serving as minister of Hamyang, Changwon, Daegu, Seongju, and Sangju, as well as minister of the private affairs.
