Standing grandly above the rocky cliffs of Namgang River is Chokseongnu Pavilion, arguably one of the most beautiful nugak buildings (multi-storied structure without walls) in the Yeongnam region. Chokseongnu (historically known as ‘Jangwollu’) has undergone eight renovations since its establishment in the 28th year of King Gojong (1241, Goryeo dynasty) and was once used as a commanding post for defending Jinju Palace in times of war. During times of peace, it was used for holding state examinations.

Although the structure was burnt down during the Korean War, it was restored in 1960 through the efforts of the Jinju Historical Site Preservation Society. The roof design features a mix of hipped and gabled styles and the stone pillars were built with rocks collected from Chokseoksan Mountain, located in Changwon-si. The wood used for the structure was brought from Odaesan Mountain, situated in Gangwon-do. Noticeable features of Chokseongnu are the four engraved signboards and a board that holds the works of renowned poets and calligraphers. Jinju Namgang Yudeung (Lantern) Festival is held every fall at the Jinjuseong Fortress.
