The Union Hospital was built on a corner. On the first floor was a clinic, and on the second a residence. The first floor clinic included consulting rooms and a parking space. The building has been donated to the Taipei City Government, and the first floor has been restored in the original style of the Japanese colonial era.
In 1912, Ko Chien-Liang (1896–1983) received a government grant to study at the Government of Formosa Medical School. He graduated in 1917 and in 1927 established Union Hospital at the intersection of Yanping North Road and Liangzhou Street.
Ko practiced pediatrics, dentistry, obstetrics and gynecology, otology, and venereology for about five decades. His treatment method for difficult labor made him famous and Union Hospital was one of the most sought-after hospitals in Dadaocheng during Japanese colonial rule. At the time, Chaobei Hospital in Mengjia was also very well-known and there was a saying, “Union in the north and Chaobei in the south.”
During the Japanese colonial era, the Taiping Ding street area was modernized and many Taiwanese-run hospitals were set up there: Union Hospital was in Taiping Ding Wu Dingmu and Chiang Wei-Shui’s Da'an Hospital, Li Teng-Yue’s Hong Ren Pediatric Clinic, and Lin Tu-Chung’s Ho Chun Pediatric Clinic were also all located in Taiping Ding. The restored first floor of Union Hospital is typical of a Taiwanese-run hospital in modern Taiping Ding.
Union Hospital was built mainly in imitation stone with mostly Western decoration. The pillars are of classical Ionic order, lending a classical touch to a building which otherwise has the plainness of hospital architecture of the period.
