Imgo Lecture Hall was established in Mt. Burae in the 8th year of the reign of Joseon King Myeongjong (1553) in commemoration of Sir Mong-Ju Jeong (pen name: Poeun; ï÷ÙÓñ²), the most devoted servant at the time of the fall of Goryo Dynasty, but was restored in the 36th year of the reign of Joseon King Seonjo as it had been lost during the Japanese Invasion of 1592.  Sir Hyeon-Gwang Jang (pen name: Yeoheon; íåúéÎÃ) was also enshrined here in the 21st year of the reign of Joseon King Injo (1643) and Sir In Hwangbo (pen name: Jibong; üÕÜË ìÒ) in the 3rd year of the reign of Joseon King Yeongjo (1727), but was demolished during the Lecture Hall Abolition Movement in the 8th year of the reign of Joseon King Gojong (1871).  It was restored in 1965 to enshrine Sir Poeun and Sir Jibong and was repair and beautified in 1980.  The Sacred Zoning Project since 1990 has established another lecture hall next to the existing one and thus, the scale of the site has become magnificent.  Currently, the old and the new lecture halls coexist.  

Sir Poeun Mong-Ju Jeong was born to Un-Gwan Jeong in today¡¯s Uhang-ri of Imgo-myeon in the 6th year of the reign of Goryo King Chungsuk (1337) and won the first place in the government examination in the 9th year of the reign of Goryo King Gongmin (1360).  He served as an officer at Yemungwan (Office of Loyal Messages) and a judiciary minister and played major roles in defeating the Japanese invaders and making national friendship with the Ming Dynasty of China.  As one of the three most meritorious servants of Goryo, he tried to overturn Goryo's fall, but was murdered on Seonjukgyo (bridge) by Yeong-Gyu Cho, one of Bang-Won Lee¡¯s private soldiers, in the 4th year of the reign of Goryo King Gongyang (1392).  Later, he received the posthumous confernment as an honorary prime minister in the 1st year of the reign of Joseon King Taejong (1401), was named Ikyang Buwongun (ìÌåÕݤêÁÏÖ) and titled Munchunggong (Ùþõ÷Íë).
