Hwaseong (Brilliant Fortress), the wall surrounding the centre of Suwon, South Korea, was built in the late eighteenth century by King Jeongjo of the Joseon Dynasty to honour and house the remains of his father Prince Sado, who had been murdered by being locked alive inside a rice chest by his own father King Yeongjo having failed to obey his command to commit suicide. Located 30 kilometres south of Seoul and enclosing much of central Suwon including King Jeongjo’s palace Haenggung, UNESCO designated the fortress a World Heritage site in 1997. The Suwoncheon, the main stream in Suwon, flows through the centre of the fortress.
