Located about 30m east of the Daegwallyeong Seonghwangdang, this shrine is designated as Gangwon-do Monument No. 54. Inside the small tiled building, a portrait of the Guksa Seonghwang is enshrined. The image depicts the deity on a white horse carrying a bow and arrows, accompanied by an attendant holding the reins and guarded by tigers. The inscription reads "Great Spirit Guksa Seonghwang of Daegwallyeong."

In front of the shrine stands a stone statue called Subidang or Sugudang, dedicated to the "Subi," subordinate spirits who serve as messengers. While the current structure was rebuilt in 1944, its history is deeply linked to the Gangneung Danoje Festival, which dates back over a thousand years. Historical records suggest the mountain spirit enshrined here is Kim Yu-sin, the famous Silla general, a belief widely held by local residents today.

The spirits of Daegwallyeong are central to the Danoje Festival. During the festival, the spirits are moved to the Namdaecheon Danoje grounds. After the final "Soje" ritual (burning of sacred items), the Guksa Seonghwang spirit returns here to Daegwallyeong, while the female deity returns to her respective shrine.
