Keelung Fortress Command Headquarters

The Keelung Fortress Command Headquarters (基隆要塞司令部) was the supreme military command center for the defense of northern Taiwan during the Japanese colonial period (1895–1945). Located in Zhongzheng District, Keelung City, it served as the nerve center from which the Imperial Japanese Army coordinated coastal defense operations across a vast stretch of Taiwan's northern coastline.

The origins of the fortress command trace back to 1896, when the Japanese military established the Keelung Fortress Command Post (基隆要塞指揮所) shortly after taking control of Taiwan following the Treaty of Shimonoseki. In May 1903, this was upgraded to a full Fortress Command (要塞司令部), formally beginning operations in August of the same year. The command's jurisdiction encompassed the coastal defense zones of Keelung, Aodi, Jinshan, Tamsui, Hsinchu, and Houlong — effectively the entire northern and northwestern coast of Taiwan. Under the command's authority were numerous battery positions ringing Keelung Harbor, including fortifications on the surrounding hillsides designed to protect one of Taiwan's most strategically important ports.

In 1928, the Japanese military decided to construct a new permanent headquarters building. Designed by Asai Shin'ichi (淺井新一), an architect of the Governor-General's Office Construction Division (総督府営繕課), the two-story reinforced concrete structure was completed in 1929. The building adopted a T-shaped layout covering approximately 900 square meters, featuring a modernist architectural style with brown thirteen-groove face brick columns and cream-colored terrazzo balustrades. The design reflected the transition from traditional wooden military buildings to modern earthquake-resistant construction in colonial Taiwan.

During the lead-up to World War II, the fortress command's role expanded significantly. In September 1941, the main combat force was reorganized as the Keelung Fortress Heavy Artillery Regiment (基隆要塞重砲兵聯隊). By November 1941, just weeks before the attack on Pearl Harbor, the command entered a state of preparatory combat readiness (準戰備). Keelung Port served as one of the staging points for Japanese military operations toward Southeast Asia. During the October 1944 Taiwan Air Battle (台湾沖航空戦), when American carrier aircraft attacked Taiwan, the fortress defense forces engaged enemy aircraft but sustained significant casualties and equipment damage.

After Japan's surrender in 1945, the Republic of China military took control of the facility, renaming it "Guangfu Camp" (光復營區, "Recovery Camp"). It later became a station for the Executive Yuan Coast Guard Administration. The headquarters building was designated a Keelung municipal historic site (市定古蹟) in 2010. In 2017, the Coast Guard transferred the building and surrounding grounds to the Keelung City Government as part of the "Great Keelung Historical Scene Restoration Integration Plan." After extensive restoration, the building opened to the public in 2022, now serving as a cultural heritage site where visitors can learn about Keelung's military history. Since November 2023 the site has been run by a private operator as the cultural and creative venue "Commander's Grand Courtyard" (司令大院子).
