These pillars were originally taken from Gyeongjueupseong Fortress, and were only rediscovered when the fortress walls collapsed. The four square stone pillars, which had once been used as a part of an architectural structure, can be combined to form an embossed design of an erect “arhat” (enlightened practitioner) on two sides. The arhat is rendered in profile, walking to the right on a lotus pedestal; his head is bowed in deference and he holds an incense burner with handle in his hands. The tips of his shoes are bent upwards, much like those of the arhat in the “Image of Ten Disciples” in Seokguram, which was built during the Unified Silla Period in the mid-8th century.
