The Bronze Bell of Sangwonsa Temple, located on Odaesan Mountain, was cast in 725 (the 24th year of King Seongdeok’s reign) during the Silla Period. Measuring 1.67 m in height and 0.91 m in diameter (at the rim), this bell is one of only two extant Buddhist bells from Silla together with the Sacred Bell of Great King Seongdeok (National Treasure No. 29).The top of the bell has a hook carved in the shape of a dragon with a large head and strong claws, and beside it there is a hollow tube for controlling the bell’s tone that is decorated with patterns of lotus flowers and vines. Wide bands are placed around the rim and shoulder, while there are four square blocks, each containing embossed designs of lotus flowers, below the shoulder band. The bands and the square blocks are bordered with bead patterns and decorated with scroll designs and several figures playing musical instruments. Sets of two Apsaras (Celestial Maidens), kneeling on clouds and playing musical instruments, are carved around the center. Between the Apsaras, the striking points are decorated with bead and lotus flower designs. It displays brilliant carving skills, and has a convex body with a rim that is narrower than the center. It is the oldest and finest bell existing in Korea, exhibiting all the unique structural features of Korean bells.
