To us, Poseokjeong is remembered as the unfortunate place where Silla's 1000-year-long history came to an end. When we look at this photo from 1916, we can see how Poseokjeong was left unattended and uncared. Let's go back a bit and look at the political situations near the end of Silla. Silla was surrounded by Gyeonhwon of Hubaekje and Wang Geon of Goryeo. And very frequently, their villages were taken and independent landlords turned themselves into Goryeo. Meanwhile, this is what was written in Samguk Sagi: "Gyeonhwon of Hubaekje invaded Silla in November 927 and had reached Gowulboo". At that time, King Gyeongmyeong passed away, and King Gyeongae succeeded to the throne. King Gyeongae requested help from Wang Geon of Goryeo. However, before Goryeo army could arrive, Gyeonhwon invaded Gyeongju. Then, he captured King Gyeongae who was having a feast, made him kill himself, and took other royal families hostage. And Gyeonhwon put Kim Bu (later King Gyeongsun) on the throne and left Gyeongju. Afterwards, in 935, King Gyeongsun surrendered to Wang Geon of Goryeo. Hence, the 992-year-long history came to an end. Next, let's look the records in Samguk Sagi. According to Samguk Sagi, the 49th King Heongang was having a feast at Poseokjeong. Then, the god of Mount Namsan appeared and started dancing. This god was not visible to the courtiers. Therefore, the king ordered silence and kept still for a while. When the feast resumed, courtiers asked the king what he saw. And the king responded by imitating the dance he saw. This dance is known as Sangsim-mu (King Dances, God Dances). In another story from Samguk Yusa, when the same king, King Heongang went to Geumgangryeong, the god of Mount Bukak appeared and performed a dance known as Okdogeom. What's scary in the story is that the god made a prediction of Silla's collapse in a near future.
