County of city

A county of city was a type of local government area in Scotland between 1893 and 1975. There were four of these areas, covering the cities of Aberdeen, Dundee, Edinburgh and Glasgow. Each area was governed by a city corporation (also known as a town council) and was administered independently of the surrounding county. The areas were abolished by the Local Government (Scotland) Act 1973, and were replaced by regions and districts in 1975.
