Sungyang Hall is a fourteenth-century Confucian academy located on the side of Mt. Janam in Kaesong, North Korea. The hall was constructed in the late fourteenth century for the home of the famously loyal statesman and Confucian scholar Jong Mong-ju, whose 1392 assassination by the agents of the later Taejo of Joseon marked the end of the Koryo dynasty. In 1573, the building was transformed into a Confucian academy.
