City limitsCity limits or city boundaries refer to the defined boundary or border of a city. The area within the city limit can be called the city proper. Town limit/boundary and village limit/boundary apply to towns and villages. Similarly, corporate limit is a legal name that refers to the boundary of municipal corporations. In some countries, the limit of a municipality may be expanded through annexation.
Town hallIn local government, a city hall, town hall, civic centre (in the UK or Australia), guildhall, or a municipal building (in the Philippines), is the chief administrative building of a city, town, or other municipality. It usually houses the city or town council, its associated departments, and their employees. It also usually functions as the base of the mayor of a city, town, borough, county or shire, and of the executive arm of the municipality (if one exists distinctly from the council).
