Remains of Taipei Prison (Huaguang Community Ruins)

The Taipei Prison (臺北刑務所, Taihoku Keimushō) was established by the Japanese colonial Government-General of Taiwan during the early colonial period, with construction completed around 1904. It was one of the three major prisons built in colonial Taiwan (the others being in Tainan and Taichung); the new complex outside the old city walls covered 58,752 tsubo and was renamed Taihoku Keimusho (臺北刑務所) in 1924. The prison adopted a radial floor plan — a standard 19th-century penal design that allowed centralized surveillance of multiple cell blocks from a single guard station.

The prison walls were constructed using stones salvaged from the Old Taipei City Wall (臺北府城), originally built by the Qing Dynasty in the late 19th century and subsequently dismantled by the Japanese colonial government to facilitate urban modernization. This reuse of Qing-era masonry gives the surviving wall segments distinctive archaeological and architectural value.

Throughout the Japanese colonial period, the Taipei Prison served as the primary detention facility for political dissidents and anti-colonial activists. The most significant episode was the 1923 "Police Incident" (治警事件, Chijing Shijian), triggered by the Taiwan Parliament Petition Movement's challenge to Japanese authority. On December 16, 1923, colonial police arrested 41 activists, including Chiang Wei-shui (蔣渭水, Cell 26), Lin Youchun (林幼春, Cell 24), Tsai Pei-huo (蔡培火), Wang Min-chuan (王敏川), and the poet-physician Lai He (賴和). Chiang Wei-shui and Tsai Pei-huo were sentenced to four months' imprisonment; Lin Youchun, Tsai Hui-ju, and several others received three-month terms. Chiang Wei-shui famously noted that his cell had better sanitation than ordinary homes, with dedicated water channels, a private toilet, and ventilation — an ironic observation that underscored the colonial government's investment in controlling political opposition.

During World War II, in 1944 and 1945, Allied airmen who had been shot down or crashed while on patrol missions over Taiwan were detained in the Taipei Prison by the Japanese Imperial Army. Fourteen of these prisoners, American airmen, were given a perfunctory trial, sentenced to death on a charge of bombing civilians, and executed by firing squad at the prison on June 19, 1945 — just 57 days before Japan's surrender on August 15, 1945. A memorial plaque on the surviving northern wall commemorates these executed airmen.

After Japan's defeat and the handover of Taiwan to the Republic of China in 1945, the prison continued in use until 1963, when the inmates were moved to a new prison at Guishan, Taoyuan. The prison buildings were repurposed as government employee dormitories, and the surrounding area became known as the Huaguang Community (華光社區). By the early 21st century, most of the original prison structures had been demolished or fallen into disrepair, and residents were relocated through a controversial urban renewal process.

Today, a north wall section of roughly 90 meters and a longer, lowered south wall section survive beside the Chunghwa Telecom and Chunghwa Post premises, near the intersection of Aiguo East Road (愛國東路) and Jinshan South Road (金山南路). The wall segments, including the distinctive "corpse exit gate" (運屍門) — a small arched doorway through which the bodies of deceased prisoners were removed — were designated as a Taipei City Historic Monument (市定古蹟) in 1998 (north wall); the south wall was added in 2013. The former prison officials' dormitories on Jinhua Street have been restored and reopened in 2022 as the "Rongjin Time Living Park" (榕錦時光生活園區), a cultural-commercial complex that preserves the Japanese-era wooden architecture while offering dining and retail spaces.

The site stands as a tangible reminder of colonial-era political suppression in Taiwan and of the wartime fate of Allied prisoners of war — a layered history spanning Qing, Japanese, and postwar eras within a single city block.
