Gwandeokjeong Hall, which is located at the center of downtown Jeju, serves as a meeting ground as well as a milestone. It is designated as Treasure No. 322 and is familiar sight to the resident in Jejudo Island. Jejumok-Gwana Government Office was located near Gwandeokjeong Hall (Treasure 322), and used to be an area where government offices were located. From the Tamnaguk to the Joseon Dynasty, the Jejumok-Gwana served as the center of administration in Jeju. Gwandeokjeong Pavilion was built by Pastor Sin Suk-Cheong in the thirtieth year of King Sejong's reign (1448) as a training ground. On 1 March 1947, people joined the ceremony to commemorate the Independence Movement of 1 March 1919. When they left the protest site, 6 were killed and 8 were injured due to a shooting by the police. This resulted in an unprecedented general strike and later, many Jeju Islanders were detained and tortured in the police station at this site.
