Crown Prince Sado
Crown Prince Sado was buried on Mt. BaebongSan in Yangju. His body was moved by his son, King Jeongjo, to its current location in 1789, then called Hyeollyungwon near Suwon, 30 kilometers south of Seoul. Five years later the Suwon Hwaseong Fortress was built by King Jeongjo, specifically to memorialize and honor his father's tomb (the construction lasted 1794-1796, while the official reception was 1795). Lady Hyegyeong died and was buried with her husband in 1816.
