The city government was initially housed in buildings belonging to Huashan Elementary School [zh].[1] In 1940, a new city hall was opened on the same site. It was three- to four-stories tall and built in a modernist style.[2]
After Taiwan was handed over to the Republic of China on 25 October 1945, Taipei became a provincial municipality and the capital of Taiwan Province. Its city hall was established in the former campus of Jian Cheng Elementary School [zh].[3] The old city hall building was turned over to house the provincial government for Taiwan. It became the Executive Yuan building in 1957.[1]
The Republic of China government was forced to retreat to Taiwan in 1949, and Taipei became the nation's seat of government. In 1967, Taipei's status was upgraded to a cabinet-level municipality. Its service thus grew much bigger with the large increase of population. Taipei's city hall could only accommodate around 1,000 employees, and many other units were scattered in various rented offices.[4]
There are 5 internal administrative branches, 22 departments, 7 offices, 4 committees, and 2 public corporations, under the head of the city, the mayor of Taipei and the vice mayor.[5]
