A fire broke out at Gyeongbokgung in Jongno District, Seoul, at about 5:30 a.m. on the 28th. The blaze was extinguished in a little over 10 minutes, but part of the door of Jasundang (資善堂) was damaged. Built in 1427, Jasundang was the quarters in Gyeongbokgung where the crown prince and princess resided.
According to the Korea Heritage Service that day, a fire broke out at Sambimun (三備門) near Jasundang at Gyeongbokgung. A safety guard patrolling inside the palace spotted smoke and put out the fire with a fire extinguisher and other equipment. After completing initial suppression, the Gyeongbokgung Management Office reported the incident to the fire authorities.
The fire damaged one auxiliary pillar of the side door next to Sambimun and part of the sinbangmok (信枋木). Sinbangmok is a base timber fitted under a pillar. There were no casualties. The Korea Heritage Service said, "As a result of investigating the cause with the fire department and other related agencies, the blaze is presumed to have been caused by spontaneous ignition," adding, "Repairs are underway in the area around the damaged Sambimun."
Gyeongbokgung opened as normal that day. Around 9 a.m., the Gyeongbokgung Management Office installed a screen near Sambimun and adjusted the viewing route. Huh Min, commissioner of the Korea Heritage Service, visited Gyeongbokgung that day to inspect the site.
