Abstract
A derelict bridge called WoljungGyo is being restored in Gyeongju, the capital city of ancient Silla. WoljungGyo was originally built in 760AD, and later rebuilt in 1280AD during the Goryeo Kingdom. The bridge lasted in working condition for at least 520 years. The bridge was uncovered to the remains of both abutments and four piers, with only one or two steps remaining. The provenance of the WoljungGyo stone relics was investigated to decide the type of stone for the restoration works. Field survey were carried out in the whole area of Gyeongju-Si with petrological investigation for the stone relics. Results of the study present that Namsan granite was used in those days for building of the WoljungGyo. It is seems that the used stones were obtained from tor or core stone around the Tongil-jeon and Tap-gok area in the east side of Mt. Namsan.
