A royal villa stood here during the Silla period(57B.C.-A.D.935). Except for a stone water channel shaped like an abalone, all the facilities including pavilions have long disappeared. It is believed the king and his officials enjoyed poetry reciting games here floating wine cups on the channel.
According to legend, the god of Mt. Namsan came and danced when King Heon-gang-wang had a party here. The king danced after the god, thus starting a Silla dance known as "Eomu sansinmu(King Dances, God Dances)".
King Gyeong-ae-wang(924-927) met a wretched death at the hand of Gyeonhwon of later Baekje while having a party here. Thus the location symbolizes the demise of the thousand-year Silla kingdom.
Poseokjeong, the most beautiful alternative palace of Silla Kingdom, and Historic site No.1, is located one-kilometer from Najeong along the road to Eonyang. Now at Poseokjeong, the abalone-shaped stone channels through which a cool stream of water was directed during royal banquets can be seen. Stone channels were made for recreation. A cup of wine was set afloat and a specified guest was challenged to compose some verse before the cup reached a turn in the channel. This activity goes back a thousand years to China. It is rarely practiced now.
The water channel of Poseokjung is becoming a valuable material. There are no records of when Poseokjeong was built, but it is certain that Poseokjeong and the stone channel were made during the unified Silla. Samkukyusa has it that King Hungang went to a banquet at Poseokjeong with his ministers, and enjoyed himself dancing and drinking.
The stone channel is assembled with 63 stones and 10.3m long, 5m wide and 50 deep.
Around Poseokjeong are several hundred year old willow, pine, and bamboo. Along with rocks of Mt. Namsan, the location is beautiful. The water of stream running around Poseokjeong is believed to be drained to the stone channel.
