In local government, a city hall, town hall, civic centre (in the UK or Australia), guildhall, or municipal hall (in the Philippines) is the chief administrative building of a city, town, or other municipality. It usually houses the city or town council and at least some other arms of the local government. It also often functions as the office of the mayor (or other executive), if the relevant municipality has such an officer. In large cities, the local government is often administratively expansive, and the city hall may bear more resemblance to a municipal capitol building.
By convention, until the middle of the 19th century, a single large open chamber (or "hall") formed an integral part of the building housing the council and such other organs of government as supported it. The hall may be used for council meetings and other significant events. This large chamber, the "town hall" (and its later variant "city hall") became synonymous with the whole building, and, synecdochically, the municipal government headquartered there. The terms "council chambers", "municipal building" or variants may be used locally in preference to "town hall" if no such large hall is present within the building.
