Suwon City Walls (화성)
Often referred to as “Suwon Castle”, these fortifications actually constitute a walled city called Hwaseong by the Koreans. Constructed by the order of King Jeongjo from 1794 to 1796, the terrain-following walls are definitively characteristic of Korean fortifications throughout history. The crenellations and supplemental structures along these long ramparts reflect a mixture of Ming and Qing Chinese influences and represent the last major fortification constructed by the Yi Dynasty before its demise.
The walls stretch a total of 5.7 km and vary between four and six meters in height. The fortifications include command posts, four main gates, sentry posts, “secret” gates, observation towers, crossbow platforms, a pair of fortified floodgates, and several pavilions, all of which have been beautifully renovated over the past forty years.
Hwaseong was never attacked and so we'll never know how well these fortifications would have held up under assault. Instead, the elegant walls and imposing turrets provide still today some idea of the majesty surrounding the Kingdom of Joseon at its height.
