The road over Gyerimnyeongno Path was opened in 156, the third year of the reign of King Adala of Silla, according to Samguk sagi (History of the Three Kingdoms). Haneuljae, meaning “Sky Pass,” refers to a hilly section of this road running from a temple site in Mireuk-ri to Mungyeong. The area has a history of constant territorial conflicts between Goguryeo (37 B.C. - A.D. 668) and Baekje (18 B.C. - A.D. 660). Small valleys along the ancient road look beautiful against the scenic backdrop of Woraksan Mountain.
