Suwon was one of four main regional government centers during the Joseon dynasty. Hwaseong Fortress, built to protect the city, was designated as a UNESCO World Cultural Heritage Site on December 12, 1997 for its historical value. The fortress offers various performances daily as well as the Suwon Hwaseong Cultural Festival every fall. The walls stretch for 5,700 kilometers, with Paldalsan Mountain at the center. The fortress, constructed from 1794 to 1796, was built as a display of King Jeongjo’s filial piety towards his father and to build a new pioneer city with its own economic power.
