Designated as a National Heritage on January 21, 1963. Standing 5.1m tall and made of granite, the two pillars face each other north to south with a 1m gap in their original positions. While roof tile fragments found nearby suggest this was a temple site, no historical records remain. The pillars are simple with no carvings on the inner or outer faces, except for slightly beveled edges on the outside.

Since the original base stones are missing, the exact structure is unknown, but the rectangular foundation stones suggest the base was also rectangular. Its simple style and sturdy execution are very similar to the flagpole supports at Mangdeoksaji (Treasure No. 69), leading experts to estimate its construction around the 8th century.

Located in the heart of the city, the two pillars stand facing each other. It may be difficult to imagine the original appearance as the base that supported the flagpole is gone. However, its simple and unadorned form reflects the aesthetic of its time. Its central location makes it an easy stop during a city tour.
