The ceremonial county of Somerset, England, is divided into 418 areas known as civil parishes, which are subnational entities forming the lowest unit of local government in England. Parishes arose from Church of England divisions, and were given their current powers and responsibilities by the Local Government Act 1894. Somerset consists of a non-metropolitan county administered by Somerset County Council, divided into five districts and two unitary authorities. The districts of Somerset are West Somerset, South Somerset, Taunton Deane, Mendip and Sedgemoor. The two administratively independent unitary authorities, which were established on 1 April 1996 following the break-up of the county of Avon, are North Somerset and Bath and North East Somerset. The city of Bath is the largest centre of population in Bath and North East Somerset. Areas of the city that were formerly within the Bath County Borough are now unparished, but the rest of the authority is divided into 49 parishes (Keynsham pictured). South Somerset is the largest of Somerset's five districts, covering an area of 958 square kilometres (370 sq mi) from the borders with Devon and Dorset to the edge of the Somerset Levels.
