Calgary City Hall (often called Old City Hall or Historic City Hall), is the seat of government for Calgary City Council, located in the city's downtown core of Calgary, Alberta, Canada. The historic building completed in 1911 serves as the offices for Calgary City Council, consisting of the office of the Mayor, fourteen Councillors and municipal Clerk. Calgary City Hall originally housed the municipal council and portions of administration from its completion in 1911 until the construction of the Calgary Municipal Building adjacent to Old City Hall in 1985, which currently houses the offices of 2,000 civic administrators.
Calgary City Hall is designated a National Historic Sites of Canada, as well as a Provincial Historical Resource, and Municipal Historical Resource.
