Okyeonjeongsa was the private retreat of Seo-ae Ryu Seongryong, a high-ranking official who played a key role in repelling Japanese forces during the Imjin War while accompanying King Seonjo. He built this residence to educate younger members of his clan and to engage in scholarly discussions with guests. Perched on the edge of a cliff and originally accessible only by boat, the house became his place of seclusion after his family home in Hahoe Village was destroyed in a major Nakdonggang River flood. It was here that he wrote Jingbirok, a reflection on the Imjin War, now designated as National Treasure No. 132.
