City and town halls
A city hall or town hall is the headquarters of a city or town's administration and usually houses the city or town council, its associated departments and their employees. It is also usually the base of the city, town, borough or county mayor.
In the United Kingdom, Australia, New Zealand, Hong Kong and many Commonwealth countries, "town hall" is the more common term. During the 1960s many of the older town halls were replaced by "Civic centres". The civic centre was a functional building, offices of the council only, without the art gallery or hall for cultural activities which were a feature of many of the older town halls.
"County hall" is used for the headquarters of County council administrations.
