Hwaseong Fortress in Suwon was built by King Jeongjo, the 22nd ruler of the Joseon Dynasty. The king’s father, Crown Prince Sado, was involved in political strife and met a tragic death in a rice chest, never ascending the throne. King Jeongjo moved the tomb of his ill-fated father to Mount Hwasan in Suwon. In the process, local residents had to be relocated, and the fortress was built for the construction of a new town for them. Hwaseong Fortress comprises a dazzling array of science and technology from the East and the West in the 18th century. The castle is preserved in its original state nearly perfectly. With both military and commercial functions, it is the most beautiful and practical fortress in the world.
