Hwaseong Fortress or Suwon Hwaseong is a Korean fortress surrounding the centre of Suwon, the provincial capital of Gyeonggi Province, South Korea. It was built from 1794 to 1796 by King Jeongjo of the Joseon dynasty to house and honour the remains of his father, Prince Sado. Sado had been executed by being locked alive inside a rice chest by his own father King Yeongjo after failing to obey a command to commit suicide.
