County town

In Great Britain and Ireland, a county town is usually the location of administrative or judicial functions within a county, and the place where public representatives are elected to parliament. Following the establishment of county councils in England 1889, the headquarters of the new councils were usually established in the county town of each county; however, the concept of a county town pre-dates these councils.

The concept of a county town is ill-defined and unofficial. Some counties in Great Britain have their administrative bodies housed elsewhere. For example, Lancaster is the county town of Lancashire, but the county council is in Preston. Due to the creation of unitary authorities, some county towns in Great Britain are administratively separate from the county. For example, Nottingham is separated from the rest of Nottinghamshire, and Brighton and Hove is separate from East Sussex. On a ceremonial level, both are in their own respective counties geographically.
