The roads linking Paldalmun and Janganmun Gates and l inking the Royal Country Palace and Janganmun still frame the key traffic network in the city as they have for 200 years. One of the restoration problems is that the original bricks and roof tiles were produced by a special method which is difficult to reproduce by present techniques.
Continuous research is required for better preservation.
Because of the nearby main city streets, the four cardinal fates are exposed to smog and vibration from vehicles, which raises concern about what countermeasures and safety management can prevent their deterioration. To prevent further damage from the urban environment on either side of the entire fortress perimeter, the government has purchased and designated the area up tp 20 m inside and outside of the fortress wall as a preservation zone and turned it into a green belt of lawn. The area 100 m inside and outside of this preservation zone is designated and protected as a cultural property zone. The seven unrestored facilities and demolished parts of fortress wall amounting to 493 meters are due to be rebuilt in accordance with the long-term restoration plan. Wooden buildings are to be protected by fire proofing and the periodic application of insecticide and the city is searching for various measures for permanent preservation.
